[Q] How to enable USB Audio streaming?

Hi everyone,
Is there a way do enable the USB Audio streaming on the HTC One m7?
I know from factory HTC doesn't allow this (don't know why) but I need it in order to be able to listen music on my car (with Gromaudio kit).
From Gromaudio website info:
Android
USB Audio Streaming on Jelly Bean and up Android phones, without AALinQ
USB Audio streaming (without AALinQ) is supported as long as Android phone is running Android 4.1 and above. Most but not all Android 4.1+ phone support USB streaming due to the way some phone companies leaving this feature out in their version of Android.
You will have to enable USB streaming using a config file. Check the instructions on the forum.
With the config file loaded, any application on the phone (i.e. Pandora, Spotify, Navigation, etc.) will have its audio redirected through the GROM in clean digital audio. There will be no track control though with any of these application also if stereo supports text, song info will not not be displayed (on AALinQ the text is supported.)
Please note that with the USB streaming config file loaded AALinQ will work just like other applications with no track control or song info. If you would like to re-enable the AAlinQ controls and text, you will have to either reset the GROM unit by pulling white connector to disconnect power from it or load another config file to turn it back on which would be config file with gromusb2.cfg with a= 1 instead.
Known limitations are: HTC phones are not supporting USB Audio streaming. Other phones, including Samsung and Nexus Android phones, do support USB streaming.

Unfortunatly I dont think it possible, I tried the same thing, messed about for days trying and ended up just buying one of these, I guess it HTC's way of just making a little bit more money, I even tried car mode, that didnt work either, I started with a 1 meter long 3.5mm to 3.5mm cable, but that just got in the way.

Well with Grom it works to listen music in the car if you use their AALINQ application from Google Play.
But you need to apply a config file and so on. But I'm not able to stream music from other apps like Youtube, Pandora or so.
But with other phones like Nexus you can do all these because the USB Audio streaming is enabled on their phones.
Not sure why HTC decided to have this feature disabled.
I've thought while having the device rooted might be a way to enable this.

Solved!
I managed to solve the issue by using pure Android Google Edition ROM for HTC One M7.
With this ROM the USB Audio Streaming is working, I can have sound in my car (USB Digital sound via Grom interface with steering wheel control) from whatever audio application I want from my HTC One (Poweramp, Pandora, Youtube, etc ..)

Are you by any chance using Lollipop? I think USB audio should be enabled on Lollipop on all devices. Not sure about the Sense version, can anyone confirm this?

I already tried with Sense version and Lollipop, the USB audio streaming is still blocked with that ROM.

[Q] USB Audio Stream Pops & Clicks

Hi All,
I have an AT&T Nexus 6 and I am trying to stream USB audio out to my car stereo. When doing so I am hearing clicking and popping in the audio. I thought it was possibly a ROM/kernel issue but I am fully back to stock & locked and the problem still exists. Audio via mini stereo jack (aux) works fine of course, as does sound coming out of the phone's speakers, headphones, etc. I have tested 2 other android devices (Nexus 4 and Samsung Nexus 10) and USB audio is working perfectly fine in my car.
If anyone has any guidance on how to troubleshoot this it would be great. This is strange to me as USB audio out was added as a software update, so I find it very odd that it works on my older devices and but not the N6. If I can't get this figured out I will have to schedule an appointment at an AT&T warranty center to likely exchange my 35-day-old phone for a fecking refurb
Thanks for any help guys, cheers!

I RMA'd my Nexus 6 and the replacement behaves the exact same way. Other non-Nexus 6 devices tested work just fine.
Has anyone actually used streaming USB audio other than me?

What app are you using to stream? I tried, but do t know if my radio wont accept it or not. I know I can't read movies from my phone or flash drive.

The idea behind USB audio streaming is that you don't need to use an app. The device streams any and all audio out of the phone via USB rather than out of the speakers. This means that you can use Spotify, Youtube, Pandora, PlayerPro, etc. while connected to your car stereo via USB and have the audio in your phone played through your car speakers in lossless digital. This is a feature that was introduced in Android 4.4 but seemingly is saught out by nobody but me.
Prior to USB audio out, these were common options/solutions, all with drawbacks:
1. Plug into the headphone jack which is an analog signal prone to noise, interference, and muddy EQ.
2. Plug into USB and Android will automatically mount your phones sdcard partition the same way as USB thumb drive. This only works for playing media files that are saved directly to the phone. All other sounds/apps do not work through as the phone's audio hardware is not being used. This means no Pandora, Spotify, etc. and no controlling music from the phone. Casper, your radio is probably trying to mount your N6 this way – most car stereos do and are not expecting have a device connected that is outputting its own hardware-driven digital audio stream.
3. Bluetooth. This was the best solution as it uses the phones audio hardware and thus all audio is output the same way as the new USB out feature. The drawback to this is that bluetooth uses lossy-compression and so is lower fidelity than option #2, though A2DP has made quality far better than it once was.
If you can't already tell, I'm sort of a fidelity nazi and this is why I'm so desperate to find a solution to this issue at hand with the Nexus 6 USB audio out that noone seems to know exists.

Any update on this? I just got my Project Fi Nexus 6 and I am regretting not doing more research on the USB streaming in the car. The iPhone 6 worked flawlessly and I could change songs with my car (I just lacked good service). The car usb won't even recognize my google play albums downloaded to my phone BUT it will pull up my zedge ringtones. Every time I try to fool around with it, it just keeps looping my Mario ringtone through my car speakers lol. But seriously, any suggestions. I am so desperate.

I gave up and went with using bluetooth. Cost me another $120 in bull**** hardware that Grom Audio sells to make this "upgrade" possible. Quality is **** compared to what it could've been as well... sigh... first world problems

I have a Grom USB2 and a Galaxy S4 that I just upgraded from 4.4.1 to 5.0.1 (Goldeneye ROM). I successfully streamed USB with KitKat (Grom has a configure file that enables their unit to do this) but have been unable to do the same thing with Lollipop. I did the *#0808# thing and tried several settings but nothing has worked. Any ideas?

Oreo Bluetooth developer options

I have experienced Bluetooth backward compatibility problems with my note 8 on devices having early bluetooth versions. For instance I have a monster rocking roller speaker that worked flawlessly with the s7 and with my N8 I would have audio distortion and crackling.
With the delivery of Oreo there are a bunch of Bluetooth settings to play with in developer options (attached) and I was wondering if anyone has had success tweaking these settings to solve an issue like I have been having.

I never used any of the settings and no BT issues here (Speakers, car audio, smart watches, wireless headphones/earbuts).
Maybe your speaker has a problem...

Have you tried messing with the sound-alive settings the phone uses? The drivers it uses suck! Ive noticed in some cars it was the issue, ive moved away from samsung drivers all together and use viper for a solution but being unrooted your stuck with using what you got

I didn't but I changed the codec setting from acc to sbc and messed with the sample rates and I now don't have a worthless $200 speaker. This seemed to solve my previous problems.

I've been having a similar issue my stereo in my truck is supposed to launch my Bluetooth music players and allow me to control the music player from the stereo in the truck but it does not now since the update any idea on what settings I should use for what they were before the update?

I use the aptX codec on my Bluetooth headset. What's up??

Bluetooth dropouts when using stereo speakers

This is a long shot.
I have a pair of Bluetooth 4.1 Minirig speakers that can be set in stereo mode. However when in stereo mode one channel experiences dropouts. Running in mono mode is fine.
The issue is with the Nokia 7+'s Bluetooth transmission as when using other Bluetooth enabled devices to power the speakers the issue does not occur.
Anyone else had this issue when connecting stereo speakers or headphones and know of a solution?
I have checked: System > Developer Options > Bluetooth Audio Codecs and tried changing these setting but the changes did not "stick" and problem remained.
Maybe there is an alternative setting somewhere that can be tweaked.
Thanks in advance.

I'm also having this issue: whenever I'm connecting my N7+ onto the car's audio system via Bluetooth I have to change the codecs to the correct one every single time to make it properly work (have sound/audio at all). The settings also don't stick or are not being saved. Also looking for a solution for this, unless an update miraculously fixes it.

Same problem here when connected to my car by bluetooth. Occasionally there is a dropout. This does not happen when my friends connect with their phones (oneplus 5, samsung, allview. or my old lg g4).
Changing the bluetooth audio codecs does not work as it does not remain selected and it switches to default. This, as i understood, happens on android 8 and has been resolved in the Pie beta and should be ok in the final Pie release.

When I raised the issue with the superbly talented nokia tech support they either act surprised as if its an unique issue to you or send you a list of compatible bluetooth protocols. Are we expected to change our cars and speakers to make the phone work?

I had this issue after installing garmin connect. Theres a thread over in the garmin forums (forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-android/1375800-audio-streaming-issues) about it. Also on the nokia forums (community.phones.nokia.com/support/discussions/topics/7000022239/). Seems to affect some phones on 8.1
Anyway, I'm on Pie beta now and the problem has gone away.

USB Audio out?

Hi guys, I've noticed that when I connect my DAC to the type-c port on phone there's no audio.
Is there no sound routing through this interface?
Can it be enabled?
Thanks

I've noticed same thing.

Have you checked the "USB Audio Routing" in Developer Option menu?

Yes I did. We should contact Sony support, it's a small issue, an update will fix it easely.

I've tested only with Sony DAC from my Xperia XZ2. Maybe that one isn't compatible.

Maybe the Sony is passive, in that it passes through audio from the phones amp. The Meizu is active, it has its own DAC and Amp built in. Just a wild guess. Maybe the Xperia 1 II does not pass on audio from its built-in amp through the usb connection

USB-C audio works fine with the cable from my old Pixel 2XL. No settings needed.

I've tested using a Hidiz Sonata USB device and the USB audio player pro app and it'w working fine here.

XD05 Plus not connecting.
Doesn't seem to work with Xduoo XD05 Plus
The volume/power from the phone is barely okay for my IEMs, but it can't drive any of my headphones.
This was supposed to be an upgrade from my LGV30 (works fine with XD05) , unfortunately it's rather looking like I should have gone for a V50 or V60 instead.
I have checked in the developer options and it seems like USB Audio Routing is on by default.
Any recommendations to get it working would be appreciated.
I have just tested with my Dragonfly Black and that seems okay. At least it has sufficient power to drive most of my headphones to a reasonable volume. Still very keen to get it working with the Xduoo if I could though.
