USB Audio Output - Samsung Epic 4G Touch

Well, I finally found out you can get audio out of the USB port and grabbed a cable from eBay. Thought life would be grand. Got the cable and it works. Still grand.
Then the problems started. Horrid pop, crackle, hiss, beeps, and bloops. Did a little homework and found apparently it's a realatively common problem, but can't seem to find much detail.
Anyone know of any fixes other than a warranty swap out as I'm sure we're well past that point now.
Thanks in advance.

Wait, so analog audio out of the USB port? Why not just use the mini headphone jack?

One cable to rule them all. This way I plug in one cable (work or car) and listen to audio and charge the phone at the same time. I'd use bluetooth in my car, but Velosters have an absolute crap bluetooth when combined with this phone.
It's just easier and less to deal with.

Headphones for XDA Orbit

Does anyone know if I can get other headphones for my XDA Orbit? Because of the mini usb connector factor - I am thinking it may prove tricky or can we use the mini usb to 3.5mm jack I have heard mentionned ?
i have tried a Motorola V3 mini usb to 3.5mm adapter with my MDA Compact3, it didn't work!! sounds continued to play though phone, no sound though headphones.
This is what you need: http://www.expansys.com/p.aspx?i=142090
It converts the strange HTC 11-pin mini usb to a 3.5mm socket
Not in stock yet though.
is ther an adapter that functions simaler to the sony phones adapters, it goes from the port on the phone to a smapp 3.5 jack and microphone, then any earphones can be plugged in, so that you get to use ur own eaphones but can still use it to make and recieve calls

Thanks TheBrit That jack looks like it would fix the issue of different headphones but I wonder would there be any issue with the FM radio. I was thinking could you do a magiver ,using the existing usb headphones but solder different headphones from the microphone part might also be the way forward if that makes sense!
yea, that's wat I was saying, have a headphone socket after the volume control and mic...
I imagin this would solve the problem of the radio aswell...
Well, Thanks for the ideas - went to Maplins and bought an inline socket - followed this tutorial and happy days !!

Headphones and Carcharger

Would it be possible to wire headphones and charger to a mini usb plug in order to charge and listen to headphones at the same time? When using Gps and headphones battery life is limited.

How about an adapter that provides a regular 12V DC jack for charging and a 3.5mm stereo mini jack for output to the car stereo AUX input?
Now that WOULD be useful. Maybe the Brodit active mount provides something like that?

Almost. If I was being picky (which I am I'd say the second USB port makes it a bit bulky. Ideally it would just have 1 USB and 1 3.5mm jack.
No rush though. I'm sure we'll be seeing a lot more.

Microphone lost
Hi, I've bought a splitter from here: http://www.valuemax.co.uk/product_details.php?id=7184

[Q] Audio line-out for Galaxy Nexus

Hello all ,
Is there a way to get an audio line-out from the Galaxy Nexus, either using an adapter or a docking station? I'm not looking for a solution like the one offered by the Samsung Galaxy S2's car dock (which streams bluetooth audio from the phone to the dock, then the dock turns the bluetooth streaming to analog audio through a 3.5mm port) but rather something like an adapter for the MHL port or from the docking station.
Appreciate all the help!
The obvious solution (at least to me) is to plug into the headphone jack. You could also use either the media dock or MHL adapter in conjunction with an HDMI-to-analog adapter such as the one linked below:

He's asking for a line out solution because it will bypass the internal headphone amp that is utilized when the 3.5mm port is used. If you're plugging the phone into speakers or a sound system that way you'll get much better sound.
If the mhl -> HDMI cable adapter carries both audio and video, you could use an hdmi breakout adapter to split the digital audio. It depends on the HDMI output capabilities of the phone and the acceptability of digital audio for your needs.
Edit: would no doubt be a cumbersome solution. It all comes down to your usage scenario for the output.

Thank you vespoid, ardabey.
What OJ in Compton said, I'm looking to bypass the internal headphone amp, not sure if there are any details on the car dock or desk dock, I hope 3rd party manufacturers come up with something, any solutions are welcome.
Ali
Never thought about this, but a contactless dock with HDMI out directly to the AMP = audio bliss. Thanks to the forum for letting me see the obvious
Bumping this thread...has anyone successfully done this? I want line out audio for my car's 3.5mm AUX input - had it with my ipod and it sounded much better than through the headphone jack, as well the convenience of not having to maintain two volumes.
Hoping the official car dock that uses the 3 pin connector and has a 3.5 out would do this, but I'm worried it will just use BT to transmit the audio to the dock like I read the Nexus One dock did.
I wish too that the NG had line level out.
I think it's a limitation of the hardware. I think Apple is the online one that really uses line level out via it's dock connector.
I hope someday Google will use some sort of line level out on their reference hardware or built support directly into a newer OS.
I remember my old Dell DJ had line level out. Soooooo much better.
There is nothing wrong with the 3.5mm output sound quality wise.
Trying to drive headphone-like impedance (lower) with a line out isn't the best idea, but driving higher impedance inputs like your car deck isn't that bad as long as you let the amps do the "work" of boosting the volume and not your phone. While not optimal, the decrease in sound quality shouldn't be very noticeable.
The main advantage of the digital audio though USB (what apple does) IMO is that it eliminates the need to have both the USB plugged in to charge and the 3.5 mm cord for audio. It also allows song data to be shared and device control from the speaker/head unit. Good setups will recognize most android devices as mass USB storage and provide the same functionality, but I'm not sure how the MTS on the GN will affect this.
I would wait and see how the audio quality is from the dock. Even if it is bluetooth, the audio quality may not be that bad.

The problem is, that if the head unit supports MTP then yes it can read the device like mass-storage, thats fine, but it doesn't allow you to stream media from radio apps, youtube and turn-by-turn directions from gps, this is what we are looking for...
technically it's not sending analog audio output through the USB, its just reading the stored media on the phone.
I have read that samsung phones are able to accomplish sending analog audio through the USB while charging, with the correct resistance values (adapter) or possibly with software pointing the audio in that direction (for example code build into the framework/API)
this is one major thing that Android lacks over iPhone, this problem should be addressed ASAP. I'm hoping CM9 might be able to find a solution for this.
I agree, i hope they fix this soon toi. It would make the development of accessories much easier for all android phones. Seems like a no brainer but I guess Google has other priorities...

Just starred this, if the hardware is able to do that I find it completely stupid that they do not allow it.
Smartphones audio amps are not exactly famous for being top-quality so having this possibility would be great.
Thanks. The lack of this feature is ridiculous/mind-boggling/suprising.
Well, if you were waiting for the card dock to solve your problems... it doesn't. Plugging into the dock's "line out" gets you amp driven sound. I really do not understand why this is such an issue for Android. When I plug somoething into my 3 year old Nokia smartphone a window pops up for me to choose headphones, headset or line out. Why can't ICS offer the option and if in the car dock, default to line out? A USB solution is not going to help if you are using the car dock.

Which if I understand correctly uses Bluetooth to transmit compressed audio from the phone to the dock, then delivers it through the 3.5mm jack. Why not just have a digital signal go through the USB port!?

actually the pogo pin transfers the digitial audio and the dock decodes it into analog to the 3.5mm output

[Q] Who here is using a DAC & MHL? [EDIT - SOLVED - USE USB OTG INSTEAD]

I'm not an "audiophile", but I probably have more critical ears than most when it comes to quality sounds. And the GSIII isn't impressing me like I hoped it would. So I'm looking to squeeze as much out of the GSIII experience as possible, while also getting a good music experience.
So, I ditched Bluetooth and finally got USB audio when docked (thank you, CM).
But still not really impressed. Now I'd like to try these DAC things. But I have zero experience with these.
What I want is to store all my 320kbps MP3's and my FLAC's on my phone. And be able to hook my phone up to my car stereo, garage stereo and home stereo's.
One thing that concerns me is the car experience. How do you guys handle things like call audio and system sounds and GPS navigation voice?
Is it like with Bluetooth & USB audio where you hear everything without having to change inputs?
So if I plug my phone into an MHL and plug that into an HDMI to digital audio converter and plug that into a DAC and plug that into my car stereo's 3.5mm or stereo RCA input, I know that I'll get great/better music (right?!?).
But will I also get call audio and system sounds and navigation voice through that same DAC input to the car stereo? Or will I have to change an input for this to happen?
edit: Forgot to mention that I have no interest in video output at all. All I want is to get digital audio out of my phone! And I'm running a CyanogenMOD hybrid ROM.
edit #2: Oh snap, what is this USB OTG thing? Looks like something I need to research. Could be a way of getting digital audio out of phone without messing with some of the other crap.
http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/270#post_8660606
EDIT #3: Yep, looks like a USB-OTG is all I need to connect my phone to a DAC. See attached pic.
Now just need to research and figure out if there is a way to charge the phone at the same time.
Edit #4: Kk, it looks like you can plug a DAC into your phone and have the phone also charge at the same time. This thread talks about it and also points to the $6 MHL adapter that is capable of doing this:
http://rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/page__st__60
edit #5: Found a USB OTG cable with Y-cable to charging, for sale here in the USA for just $4 more than the Chinese folks. I just ordered it.
Now to buy a DAC (found a FiiO E7 on local craigslist for $35).

USB C + 3.5mm Cable?

I bought this "3 in 1 USB C Aux Adapter" cable to use in my car but it doesn't seem to work right with my car for some reason.
When my Pixel 3 is plugged into the USB C side it only outputs the left channel
When my Pixel 3 is plugged into the 3.5mm w/ an adapter it only outputs the right channel
With my iPod Classic plugged into the 3.5mm side it seems to output both L and R channels
Anyone know of a similar type cable that definitely works with the Pixel 3? I don't really want to have to use an adapter.
::EDIT::
Well, slightly embarrassing but I actually wired up the aux cable incorrectly in my car. All is well and the cable works properly.

Let me preface...I'm definitely not an expert in the whole audio conversion area. I did start doing some light research a while back regarding USB-C --> 3.5mm adapters because I noticed that the dongle provided with the Pixel 3 caused sound quality issues with my 3.5mm Bose buds. I fly on airplanes a lot and noticed the sound output volume is significantly less with the dongle and 3.5mm headphones than using the USB-C Pixel buds. From what I've been able to gather is that the digital audio converter (DAC) chip built into most of these dongles is garbage or nonexistent.
Regarding the 2-in-1 adapter / chargers...I was also looking to buy something where I could listen to my 3.5mm buds and charge my phone at the same time BUT I stumbled across some article that basically said none of those work. If I remember correctly it had something to do with the phone itself, I think it was software related?? Maybe do some searching on this but I remember reading enough stuff where it sounded like a scammy product line so I didn't purchase. Maybe this has something to do with your L vs R channel issue??
Back to the regular dongle converter...you know how things are on Amazon sometimes, 3rd party vendors can be shady and say something is higher quality when it's really not which has made me hesitant to pull the trigger on a slightly more expensive dongle. That said, I finally purchased one today that is definitely a bit more expensive than others but it seems legit and I've found reviews in other forums referencing it. Here the link: https://www.adv-sound.com/products/accessport-lite (it can also be found on Amazon).
It should arrive in a few days so I can report back but I'm keeping my fingers crossed that audio output volume / quality isn't lost like it is with the standard dongle.
Alright, the Accessport-Lite (APL) converter arrived today. Here's what I think...regular 3.5mm headphones (I'm using Bose buds) into APL into device are definitely higher quality sound than using the converter that came in box with Pixel. You can hear more background noise, overall it's more crisp and max volume is a little bit louder, not as loud as I was hoping for however but an improvement that will make a difference when flying.
Another option...I picked up a 3.5mm splitter months ago so two people could listen at the same time. I noticed that 3.5mm headphones into splitter into Pixel box converter into device actually has higher max volume than simply headphones into Pixel box converter. Go figure. Splitters are really cheap at electronic stores. Although, I would recommend buying one from the audio equipment section as opposed to the phone section. They really upcharge you for the same exact thing that's supposed to be "specially made for a phone" which is garbage.
I also tried 3.5mm headphones into splitter into APL converter, sound quality wasn't noticably better than just APL. If anything some of the crispness seemed less.
Pixel Buds straight into device remain the loudest option. However, they do not cancel or shut out loud background noise like when flying so peak volume means nothing.
Long story short...I'm decently satisfied with the APL converter. Didn't blow me away but you can tell it's quality made and every but counts when trying to overcome loud airplane noise.

I've been using the Apple USB-C to 3.5mm adapter for half a year. I like it: the Google adapter was too loud on lowest volume, and had an issue with echo in calls when using earbuds with a mic (Shure SE215). The Apple fixes all these issues and is smaller and lighter.
