Installing an aux port - MTCB Android Head Units Q&A

Has anyone figured out to install an aux port to the android head units? I have a joying headunit.
I thought that just installing a rca to aux cable to the rca input ports would work but can't get anything to play from the aux port.
Do I need to launch a specific app? I tried AV-in app but just get a error sign. Any help would be appreciated.
I tried using a cable like this

I have a cable just like that, and it works fine for me, The error sign is still their (presumably so you can't see video in), but I hear the input fine.

Yeah, just use av-in app
You have no video hooked up, so it won't show video input but sound will work

Found out that the headphone jack of my phone was not working properly.
Thanks for the help! Works now

When it comes to the error-sign:
As @Brendo said it is supposed and expected behaviour.
I remember there has been an app mod without that error sign. You could have a look over at Software-Section. There is a thread with modded MTC Apps

[Q] Headphone Jack issue?

I'm sure I'm not the only one who has experienced this issue as Google shows. Has anyone found a fix to the stupid headphone jack not working thing. How if you use certain devices the phone will not output audio. Like the aux in my car or at my work? BT works fine. Headphones work fine its mainly aux. Unplugging the device and replugging it a few times will eventually solve the issue. the thing I think is funny. I plug my aux in and it shows the little aux symbol on my phone in the status bar. but as soon as I start Google Music, it goes away and disables the aux cable. obviously that is a software thing. Is anyone working on it?

Stupid lg it's always something with them so the best fix is to rub your aux cable.... Can't wait for cm but thank you for the threads
EDIT: tried soundabout, fixes issue at least for me thanks bfranklin!
settings:
Soundabout service > auto restart
Wired Headset Behavior > all checked but the last one

I run soundabout pro and never any issue with my aux out with any device I was plugged into
Soundabout only somewhat works for my headphones.. Powered headphones really confuse the crap out of this device.

Toggle google voice search on/off

Anyone point me to a dev who could write me the change to source that would allow me to toggle google voice search disable/enable from my homescreen please...?
I have the issue where plugging in my aux cable to run my device thru car audio system annoyingly triggers google voice search as soon as I plug in the cable to headphone jack and I have to turn it off 3-5 times as it just randomly keeps turning back on and then it finally settles but then randomly the mic won't work when i get a call... it's acting buggy so I even tried a fresh GApps package to no avail.
It was fine when i had Android 4xx versions on this Z1c and started as soon as I put CM12 on it.
Weirdly the google voice search app shows as an icon in my apps list which I can happily press and open and it takes me to the 'listening' screen that annoyingly triggers on with the aux cable, but if I go to settings->apps->all there is no sign of it to try and disable....? how can it not be in there...? If there I could make a shortcut to that point. I have root but no idea where within the system files I might locate the very place I need to go.
Oh.... and plugging in the hands free headphones that came with the Z1c works perfectly and of course they have a 4 pole jack with the mic section. My aux cable is 3 pole because it doesn't need mic ability as it's only transferring the output to car audio.... and as i said this 3 pole aux cable worked fine with JB and KK.
I'm gonna try a 4pole male to 3 pole male cable when it arrives in the post, but I think this has to be a software issue.... so simply turning off Voice search as and when I choose would be a workable and straightforward solution for me.
Any help much appreciated

5.1.1 USB Audio problem (in and out) with multiple otg devices

My N7 is being used as a car headunit. I'm having a usb audio issue with multiple devices. With an OTG y cable, I am running an easycap and a UCA 202 w/an amped mic into the inputs. Everything works fine before the easycap is powered. When I swtich intro reverse, video shows up fine. When I shift out of reverse and the easycap powers off, all audio will only play from the internal speakers and I get "Can't open microphone". I have to either reset or dis/reconnect the otg y cable to fix the problem.
I am able to preserve usb audio out if I use the "easycap viewer" app but I cannot get the mic to work at all with the easycap unpowered after the first connection. Mic and audio work fine up until the easycap is powered on for the first time. Interestingly, the Mic will only work when I am in reverse. I figured this out while parked and testing--not really reasonable to shift into reverse on the highway to make a voice command .
Is there a flashable fix? An app? Any workaround?
Appreciate the help. Thanks.
Rom: Stock (LMY48X)
Kernel: Timurs v3 final (I have reached out to the developer and he said that his kernel does not modify the stock android handling of usb audio since it was built into lollipop)

HTC Max 320 Earphones on the HTC 10

Hey, guys! I've recently purchased the HTC Hi-Res Adaptive Sound 2.0 Headset (Max 320). I've tried to use those on the 10 but had no luck. These headphones which use the Type-C input should technically work on the 10 as it supports the "Hi-Res Audio", but all I get when I plug in the Headset is "Accessory not supported". Could this be a hardware issue or a firmware issue? So I wanted to ask if any of you guys have it and if you do, how did you get it to work? I've also attached a screenshot of the message.

I'd try going under the developer options of your phone and checking the USB input and changing it to see if that gets you anywhere. It'd be pretty weird if the headphones are phone specific. I have a different pair of USB C headphones that have active noise cancellation that work on my other headsets. As a last attempt, try downloading the free trial of USB Audio Player and see if the headphones work with that app.

Hey @mnguyen127! I've tried what you told me to do, by changing the input type but it didn't work. I've tried all the options in the developer settings but it didn't work out. Do you have any other ideas?

Have you tried the USB audio player app? That thing has worked wonders for me when it comes to finicky USB C
I'm in a similar situation, and nothing I've tried worked. Now, I saw someone mention something about firmware on another similar thread, so we might just have to wait for when HTC finally decides to update the 10
I have a pair of JBL Reflect Aware C which are USB-C active noise cancelling headphones, but I've noticed that after a certain update, my headphones won't work without the USB Audio Player app. Same thing happened on my Google Pixel which makes me think that if you roll back the update on your phone, you'll probably get audio out of USB-C.
the high-res certified has nothing to do with the headphone Support. the suppor for those headphones are disabled so deep in System stuff, that me and other couldn't get it to work, even with Sound stuff from u Ultra and u11. you can't use them unless HTC supports them on the 10
I still have those from the Bolt when I tested the device. but can't use them. so either HTC Needs to fix it in their Firmware or they don't want it or so. maybe the cables inside are different from other usb c Audio devices so that might be a Problem too

USB Audio Streaming

Hey everyone,
Has anyone here tried to do any kind of USB Audio Streaming with the Razer Phone? By this I mean using a USB-C to USB-A cable to play music (and other audio) from the phone to another device. Specifically, I have a GROM box in my car (2004 Acura TL) that previously allowed my Nexus 6p to play music to my factory stereo while still keeping the steering wheel controls working as well as showing track information on the factory head unit. Using the same GROM with Razer Phone however has not worked. The car and the GROM box do not recognize that the Razer is plugged in. But it will always recognizes the Nexus. So now I'm wondering if the Razer even supports USB Audio Streaming or if the only way to get sound off the phone is to use the dongle to connect to a headphone jack. Any help would be greatly appreciated.
Thanks,
Steve
