Audio - high res? - Samsung Galaxy A50 Questions & Answers

Could someone confirm if the new A50 (and presumably soon the A70 and A90 too) features high-res audio output from the headphone socket (24-bit / 192k for example)? I'm sure the chipset would support it, but not sure what the firmware allows.

Well I use Poweramp audio player which supports high-res playback, and in its Settings > Audio > Output page there should be a "Hi-Res Output" option if that feature is available. It's not a deal-breaker for me in choosing a phone from the new Ax0 range, but it'd be nice. Thanks,
Andre

You mean this setting?

Yes, that's the one. And it looks like high-res is indeed supported, thanks for checking. (16/48 is the default setting, but drilling down in Wired Headset/AUX would allow you to select higher output frequencies).

In the Poweramp app (v3), go to Settings > Audio > Output > Hi-Res Output.

(full disclosure: I'm a moderator on Poweramp's support forums, however this is not an advert for Poweramp, other high-res audio players are available...)

You can also enable high rez streaming to bluetooth using developer settings. that's how i did it(didn't know it was high rez,just thought the bluetooth audio quality was better)

(Request) JPK Froyo video 2-5 seconds long for testing

As stated in the title I need short video file download from those running on jpk. 1280 by 720. Daytime nighttime does not matter. Just playing around with codecs.
here you go
thanks a lot.
good to know that froyo brings mp4 with aac instead of eclair crappy 3gpp with amr. should be better for the concerts and loud environments now.
lol...When i first saw the video i laughed, i didnt read wat the op said, just the title...rofl
@idan - there is no significat difference with aac audio, the sound is still crappy when you record a concert.

Damn audio, totally ruins the recording/video experience with this phone...
It still is a great improvement, now I can just make a video, start AllShare and immidiately see the result on the big screen using my PS3. I always thought it was a shame to use this stupid 3GP container so I have to remux all the videos on my PC.
As for the sound: does the phone record from headset if connected? If yes, I guess this could be exploited to use a better microphone. The inbuilt one is meant for the phone function, obviously, and they just didn't add another for noise cancellation and video recording.

Fantastic. Now all we need is touch-to-focus in video mode.
another nice thing would be to be able to change the recording sound volume or some thingy that corrects its selve when you record loud things.

It is possible to record from headset but sound is still crappy. It's software problem.
The problem is with the mic itself, it is very sensitive, it would be great if there was an app that could monitor the input level of the mic and adjust de volume when its lower or higher than a certain threshold level, if not automatic at least manually.
Some kind of mic equalizer?
my bad it was always aac audio and not amr. by mistake i compared with old nexus video lol. only wrapper changed to mp4.

How to get Bluetooth HCI log? See what codec BT is using?

I enable the BT HCI snoop Log option in Dev options...but the Pixel XL does not produce a log file. (My Moto X Pure did fine)
I am trying to get the log file or some app that can read BT info to see what codec it is using to stream media.....
I have read that Pixel doe snot support AptX yet....but I want to see for myself how and what it is using to connect to my devices.
Is there an app that can give that info? with out root...
Anyone?

I have no idea about Android N, but O does.
Pixel only uses the SBC codec until android O. O supports aptX and a few other high definition Bluetooth codecs.
This I know. But doesn't help the issue of no log. My v10 also will not make a log with option checked and I k ow it supports those codecs.
On Android O....is there an Auto detecting codec setting? or if u manually select codec to use, say LDAC...and if the device does not support it, while it fall back to AptX or SBC?
I ask for anyone on the dev preview to try this and report on it.
I have Sony headphones that support LDAC...but my car headunit only supports AptX.
So would be good to know if i need to switch the setting based on device.

My Moto X Pure has the files for aptx and aptX hd....but not LDAC. I can confirm via the log and wireshark method that both Aptx/HD work.
I don't think the Moto rom and the Pixel is ASOP based...thats a separate form of android like CM and MIUI....i think. could be wrong...been too long...lol.

Is there a way to use the high quality DAC for the speaker by default?

There was a post where someone suggested using the AIMP player, I haven't been able to find it again (to give the proper credit), but it started because someone noticed how sound played different depending on what app played the sound or music.
It seems AIMP uses the Snapdragon 24-bit DSP (or DAC?) , which delivers a high quality output, I was actually surprised when I heard the difference.
My question is where or what could be changed so the default audio output uses the high quality DSP? So videos games and even ringtones and notifications (seriously it sounds much better) use it as well.
There is a great mod that activates the headspeaker when playing media, and even allows using both speakers with a stereo configuration, so perhaps using the DSP by default is also doable.
it was me who suggested the AIMP player in a previous post. i would however like to inform you that audio output using the OpenSL ES API instead of the default AudioTrack output will give you the raw audio of the DAC. Media Players which have this option will definitely sound much better. To my knowledge i have seen only VLC media player to support this feature (you have to change the output in setting unlike in AIMP). Custom sound mods are software level implementations which will just give you an amplified sound irrespective of quality. PowerAMP and MX has this option too but doesnt seem to work.
For better audio quality through speakers the default AudioTrack API works better.

Sure man, ZUK has done something which modifies the audio quality before getting into our ears. I am sure its the audio driver. If someone can change that we should get a better audio quality.
Ummm I'm so unlucky, I've my JACK bricked :silly:. And I'm finding some way to route audio through USB using "USB-C to 3.5mm converter", same as Le2. I could not find a decent type-C headphone. I use Bluetooth reciever, and it's not even close to 3.5 mm jack. Any clue ? I'VE bought Poweramp, and it's useless now.
For those who use PowerAmp, update to latest build, i.e. 704 from official forum. Zuk Z2 does support HiRes Audio Output. Latest Play Store beta channel only have 703 build, which doesn't support HiRes Audio output in N.

Maybe true, coz I found no difference even in movies with uncompressed 6 channel & 5.1 audio. But option exists, so we have hope for it to be working in future releases.
Update for Poweramp 704_universal - Doesn't work properly yet. No observable difference in quality even with flac. I've been using the 704 version for quite a while now, also on 3 different phones. None of the three have supported high res properly. On my OPX it usually caused the app to crash. Maybe with the long awaited update to v3 might make it work properly.

If, like me, your preferred player is Poweramp, you can make it sound like AIMP's OpenSL output. besides enabling OpenSL as output method, open this file /data/data/com.maxmpz.audioplayer/shared_prefs/com.maxmpz.audioplayer_preferences.xml, find the string osl_headset_float and set its value to true and save it.Then force close PowerAMP and open again, the audio quality will match that of AIMP. But anyways, if you are really a audiophile, using VLC (opensl output ofc) gives the best possible quality, just saying

[Discussion/DEV/ROM|Kernel] quad dac/es9218p on non-stock ROMs (lineageOS,etc.)

I've researched on the web for quite some time on this topic but didn't find anything definitive yet (a clear answer if it works - how to set up, etc.):
some are mentioning that only the right app would be needed to be used (well, no)
a few are mentioning that there is supposed to be an app that toggles between default dac (wcd934x) and quad dac (es9218p)
others are referring to a setting in build.prop (nope, the ROM doesn't have the mechanisms to react to that - and neither do the drivers most likely - or at least we need to make sure that this stuff is included for us)
then there are a few mentioned cases that there's support on lineageOS on board to utilize the es9218*
there's also occurences where it's mentioned that the sound stops working entirely when switching tracks (?!) - so it's still WIP
so at least the kernel needs to be set up that way - but there's probably more to it

edit:
For those who only use the quad dac for local playback (music stored on their device; NO Youtube, Streaming, etc. with Quad DAC on LineageOS/AEX/RR for now) - there is an app (for purchase) that activates & uses the quad dac (es9218p)
I've tested it and got the same specific quirk / behavior I got on LG Stock ROM with activated quad dac option.
The app is not cheap (6.99 EUR, >8 USD) - but it's totally worth it, the UI is great, the sound output is awesome (finally quad dac on non-stock !) and it uses a "custom developed USB audio driver"
extreamsd said:
This bypasses the Android audio system completely, meaning that Android's limitations regarding bit resolution and sample rate (16-bit/48kHz) are made irrelevant and high quality audio streams are fed directly to the DAC, making playback up to 32-bit at 384kHz possible (depending on the DAC capabilities) or even DSD.

Well, it's not fully "solved" - since only locally played content (no videos ! no streaming !),
but at least local content is played through the quad dac (es9218p).
So thank you very much for that hint (and everyone else who kept on mentioning it)
And: YES, the quad dac definitely is being used with USB Audio Player PRO
First I thought that the more punchy sound output could be placebo/imagination (with Xiaomi Piston V2 & the B & O Play Headphones),
but then I plugged in the Xiami Hybrid Pro (these are the only headphones that don't work with the quad dac for me - since they cause a extreme loud hissing/static on the left channel),
and after a few seconds I got the characteristic hissing on the left channel - that means that the es9218p DAC/sound card/AMP is definitely being used
That's the same behavior I got on LG Stock ROM after enabling the quad dac

In theory we would just need to write a HAL or something like that, which interacts with the kernel driver, its already there, just something needs to talk to it.
And some Overlay in the Settings to enable/disable the HAL.
The HAL would be C/++ while the Settings overlay would then be Java .... I could do the later.

It works, because the V35 files have to work on AOSP (because of treble implementation on the V35), while ours depend heavily on the LG framework (which probably does its own stuff to the vibration services), and arent supposed to ever run on AOSP.

Aha. Then score one for Treble on an LG phone that has some similar features to ours. V35 may never get bootloader unlock and root, but we can cannibalize it for the V30.

IF (a big if) volte works on GSIs (which nobody tried so far from what i know, i only know 1 person with a G7, and he cant use VoLTE, thanks to the carrier), those files are highly device specific (or atleast SoC specific), its very unlikely that those would work for us.
I could try, but dont get your hopes up on that.

I grabbed the app, it had some Network options (notably for Tidal and Google Play Music) I would assume using those options from within the app would use the DAC? Can't test personally as I'm currently using Spotify but would happily switch if I could use the DAC on a streaming service, assuming at least ~80% songs I have on Spotify are available there.

Could very well be that it provides or uses hooks to interact with those and I guess it should work (if it works, if it doesn't you can nag the devs to fix it - it's a somewhat "premium" priced app after all, and support is to be expected )
I'm not using any streaming services, sorry - so can't test.
Pretty sure there must be users of Spotify here around so maybe those can give some feedback
Edit: mistyped
Anyways I started a Tidal subscription (hifi student plan). From listening to a couple songs things definitely seem clearer but can't say for sure if it's using the DAC or placebo/better quality audio is the cause.

I probably will be switching off Spotify in favor of this; only because the student plan for it exists and I do hear an audible difference with their hifi settings ($19.99/month for hifi plan without a student discount yeeesh).
even using this app on non stock rom can we still get the same high volume output from the stock rom with HIM sound mod?

This confirms that the es9218p ("quad dac") also works with Onkyo HF Player on non-Stock :good:
So obviously these applications HF player and USB audio pro player have some line of code that is triggering the quad DAC to be utilized. Correct?

Would you still need to use higher ohm headphones to enable the quad DAC , or will this (USB Player Pro) allow any headphones to work with it?
I've got 4 sets of IEMs that I love, and would hate to have to start all over again buying new ones.

Nope, I'm using the quad/dedicated DAC with "normal", low ohm/impedance headphones myself,
the only "difference" is that there isn't much noticeable difference compared to the default (qualcomm) audio DAC
So you'll be fine,
you can choose to get yourself higher ohm headphones in the future (after careful evaluation, of course) take your time to choose the ones that best fit your hearing preferences (sound response, etc.)
Any updates on getting the dac to work with non stock roms?

Hi-Res output Snapdragon 625

Tested on the lousy zenfone 3 zoom (stock 3.5mm audio sucks inspite of DAC chip because of the poor engine optimization) and it worked like a champ but i believe other devices with SN 625 may benefit from it and they are A LOT, (use 709 build ONLY) other builds won't work as good, i tested them all.
Please do make a feedback on which other device this worked.
Snapdragon 845 devices (e.g. Sony XZ2) – improved Hi-Res Output detection
Sony XZ/XZ1 – improved Hi-Res Output detection
Lenovo X3 – reenabled 24bits
OnePlus (1st edition) – disabled DVC for Hi-Res output due to forced speaker playback
added new per-output option – No Duck – for cases when notification causes issues. Activated by default for Hi-Res output for some Snapdragon 625 devices (Asus Zenfone 3)
HTCs @ 7.0 – improved Hi-Res Output stability
Nexus 6P – fixed notification coloring
Enjoy Hi-Res music all.
Direct download, use poweramp unlocker to activate it.

Can't see any difference on the audio on Poweramp with this option set for active. The audio quality really sucks on this device.

Did you toggle the 'Wired headset/AUX" ? and was your test with headphones or via the loud speaker? and what your headphones are?
This release 709 worked for me gloriously! the only problem that it's not free and needs some work that you can find on youtube or i would post a fellow up about the odds of activating it but i just needed a conformation that it at least made a difference by utilizing the DAC chip on board!!

I've downloaded the apk you uploaded and followed the screenshots. It made zero difference to the sound quality. Poweramp DVC is great on other devices, but on my zenfone it sucks, the audio is distorted, the only way to tolerate the audio quality is by disabling it. Best player I could find so far for my zenfone is Phonograph.

The zenfone 3 zoom have an amazing sound quality and believe me the bass is insane via a good headphones, you just need to find a solution to make use of it's potentials, if you want to go throw troubleshooting provide some more information like the exact model and what software build you are currently running... you are right about the distortion i was very upset with the sound quality at the beginning but poweramp made the DAC work properly.

I wouldn't say that the sound quality on the zenfone 3 zoom is amazing. This DTS audio thing is terrible and makes sound awful. I've installed an even older version of poweramp and tried your solution, and it made a difference with my JBL T210 (not the best one around, surely). However, using Poweramp with DVC on an old Galaxy S6 that I have laying around is still miles better. Sound quality is my only complaint about this phone, that's why I was hoping for a custom rom for this thing.

Yeah you're absolutely right that DTS is a marketing thing and it sucks, you just keep trying on that poweramp 709 build only and try downloading it from APKPURE or somewhere else because the one that i provided was patched with lucky patcher and i hoped it would work with a non-rooted device to skip the activation process but apparently that is not the case, after i reflashed the phone and got rid of the root access i had to install poweramp unlocker and i have to reinstall the the main app every 2 days because without the root i can't seem to be able to activate it, keep digging, i know what a good DAC sounds like, it's not an HTC native level but it's miles ahead of the stock drivers and even better than viper4android module on magisk.

No worries about that. I've purchased the app years ago. The only thing now is that I can't allow it to update. Thanks for the hint, the sound is clearly better now.
