[Q] USB Headset speaker volume control - Shield Q&A

Hi there.
I wanted to try connecting my Razer Kraken 7.1 headset to my shield via USB OTG, and to my surprise, it worked. When changing volume though, it only seems to have 2 modes: no sound at all, or louder than my desktop speakers can possibly go. I was wondering whether it would be possible for me to change my volume somehow, so that i can actually wear my headset while playing music through it. Is there some kind of solution for this?
Thanks a lot!

Short answer, you probably can't right now.. Seems like a Android limitation.
So I've been looking around and I found a thread here for the Nexus 7 (2012) trying to sort out this exact issue. Nexus 7 USB Audio Support
(and a little more)
Basically jacknorris created some custom kernels that support USB audio out for the Nexus 7, and a mod that allows for volume control.
He also made a Flashable Zip that adds just the feature you're looking for, but it's of course for the Nexus 7. Flashing it would probably mess things up, like no audio.
You could try messaging him and asking nicely if he would help you compile a fix for the Shield, he seems to have an idea of what to do with the N7, and the Shield is pretty darn stock. It's a possibility you could supply him with the files he needs to mod and then you could test them for him.

It looks like that thread is still active though, so you could try asking there first.
It's either this, or go and file a bug report from the shield.
Even though it's really something that Google should fix.

I just sent feedback under Software Enhancement for this bug. :good:

[Q] HyperDrive RLS15 Help Please!

Hello everyone!
I have been on XDA for a while just never made an account, if you are reading this Thank-you for reading.
Recently I switched from CM10.2 to the newest HyperDrive.
I like it for somethings over others. What are you opinion on the best ROM for SGHi747?
(back to the question)
Since the install I have noticed a few things I need info on.
Bluetooth calling will not work right when headphone jack has an AUX cable in at the same time. For example hands free in a car and your phone was plugged in for music there is nothing on my end until I unplug it then the call is back over the car stereo. It is as if the ROM may need a fix for this? I can not find any setting for this; nor had this issue on any other ROM.
S4 theme (from what I read) is not avaliable on this version?
Is there anyway to remove the MegaBass that I installed during flash; without re-flashing?
Is it just me, or does my phone not make any sound when battery is low???
Anything I am missing?
Sorry for the list but I just can not seem to find it as easy to maintain or customize like Cyanogenmod. Any answers would be great, hopefully it is not too much and someone has had these issues and resolved them.
Thanks again!

Update: this isn't a Bluetooth issue. When you have an aux cable plugged in speaker phone will not work either. Is there a fix for this...? I could make a tasker profile but it seems silly to have to do that when the OS should handle it.

I have a problem with the Bluetooth headphone. Please help me!

Hi everyone.
I am using a Bluetooth head phone LG hbs730 tone+ with my nexus 5.
I don't know why the sound is so loud even when I turned off the volume on my nexus.
I tried it with nexus 7. Everything was fine
But now when I use it with nexus 5. It just blow up my head. I set the lowest sound on both my nexus 5 and my Bluetooth headphone but it is still so loud. I tried to find some app on app store but it didn't help.
Does anyone have solution? Please help me!
Thank you.
Sorry for my bad English

This is not a Nexus 5 issue. It is Kit Kat issue on all devices that use the default Google Bluedroid Bluetooth stack, meaning Nexus devices and Google Play versions (other devices running a modified stack may not be affected).
Supposedly, it is an extension to Bluetooth AVRCP 1.3 that enables Bluetooth audio devices to directly control Android's system volume. It seems some genius thought two independent volume levels (headphone volume and handset bluetooth level) was too confusing for folks. Clearly they did not think about (or test) that some Bluetooth audio devices with their own volume controls might default to a very high or low level, and control of only the handset's bluetooth level would not provide sufficient range of adjustment.
So once again we have Goofle googing up bluetooth in Android. Please share your disappointment in the following threads so that we might see a fix ASAP. Guessing they are facing law suits for hearing damage if it is not addressed quickly.

Pandora causing full volume on Bluetooth
I was having the same issue with the volume on my Motorola SF 600 headset blasting and refusing to turn down. After a lot of searching, I discovered that Pandora was causing the issue. I got it to work normally by disabling the "Bluetooth for Automotive" in the Pandora settings. It then came back. I then reverted to Pandora 4.1 and got rid of the problem. You can Google and find versions of Pandora 4.1 in the wild.
Here is more information on the helpful post.

Thanks, but I am seeing this in Pocketcasts and Play Music on both Nexus 4 and 7, and Pandora has never been installed on either of them.

Cannot play audio over USB with the Mate 8? Is it possible?

Hey there, hopefully someone can offer some insight here. I just recently got a Mate 8 and something that I did frequently with the Note 4 I had before was play audio in the car via the usb connection to my stereo. I am not able to do this with the Mate 8.
It ACTS like it's playing audio, but there's just no sound coming from the stereo or from the phones speakers. I can still change songs and play/pause it via the car stereo controls, however, which is also weird. In the developer usb options it's listed as "Audio Source", and trying to choose a mode for file transfer from the notification just causes USB to disconnect and reconnect and go back to not having anything selected. It didnt work on unrooted, unmodified, stock firmware (chinese B156), and it still doesnt work after I fully wiped all data and flashed a custom rom (KangVIP Slim).
Any ideas? Has anyone else successfully played audio over usb with their mate 8? Thanks guys.
What head unit do you own?

I own a Kenwood Excelon DPX791BH. It has two modes, one which plays local files using its android app and displays the song info on the unit and one which just plays back any audio from the phone at all, both do the exact same thing (act like they're playing, and respond to controls from the unit.) Interestingly, in the file playback mode the current time indicator on the head unit seems to run through the file at double speed. It happens with any audio, notifications or Spotify or local files, etc.
Have you tried with USB debug ON or OFF?

Where are stored your audio files? Internal memory or microSD?

the main thing i use it for is just the routing audio mode, which is independent of the location of the files. It basically functions like how a pair of headphones would if you connected it to the headphone jack and plays any audio that is produced by the phone. I've tried playing audio from the SD card and internal storage, however.
Have you tried the Mate 8 USB connection mode as MTP?

yeah, as I said in the initial post selecting either of the two USB connection options from the notification, MTP or PTP, causes the device to quickly disconnect and reconnect with neither selected.
Maybe there is an incompatibility with Android 6.
If you can you could try to connect another Android 6 smartphone.

That's what I was thinking is possible, but I haven't heard of anyone else having this problem. Has anyone used USB audio on the huawei mate 8 or any other android 6 phone? The only other phone I have is my old note 4 and that doesn't have android 6 on it.

The compatibility problem might reside in your car stereo, you might find other users of your same unit to contact on a Kenwood car stereo dedicated forum.

If anyone else can confirm audio out via USB is possible on the mate 8, then that would be the next step, as the head unit has worked with other phones in the past, and still works with my note 4. Right now asking here seems like the best idea. Hopefully someone can confirm or deny usb audio out is a possibility with the mate 8

But with which car stereo or device?
Under developer options there's a setting to enable USB audio source. The toggle is under network then select USB configuration. Not sure if this will help but worth a shot

No, sadly. Nobody has responded and it still doesn't work. Nobody has said they have been able to do it, either.

HTC U11 Bluetooth Audio Quality Issue on Android 8.0

Hi, last week I installed the OTA Android 8.0 update on my HTC U11.
Since this update the audio quality when streaming to my car's audio system or to my pioneer hi-fi system at home is a lot worse than on Android Nougat. Especially on tracks with a lot of high tunes. There's always a slight 'clink' noise. I don't know how to explain this in English..
Have you noticed this issue as well? Is there something I can do about it? Thanks
question are you using any sound mods?

Same for me. Since this update, the quality of phone call when connected to Bluetooth to my car is really bad. No problem with music stream connected to the same car.
I tried managing the new bluetooth options in developper mode menu but it doesn't solve the problem.
The codec used is all the time SBC even is I change it to AAC or aptX or AptxHD.

I have the same issue, it seems it was fixed in 42 version for US market(at least for LDAC)
I have 2 issues with Bluetooth connections with the car. The first is that it picks up interference from the noise of the wheels and engine while driving, and the sound quality suffers and it sounds unclear, unless I mute the vehicle.
The second is that it has a lot of trouble connecting to the car at times. Or, more often, it would not connect the media through the car. Don't know what's up with that.
I know how you feel
I've got exact same problem like yours. Although I'm using HTC u11 plus. My new pair of Bluetooth headphones have the same not OK audio quality. You're right especially the high tunes. I'm desperate, trying to reset everything, but doesn't help. If you find the solution, please let me know. Thank you.

Same issue here. I have the U11 as well and just updated to Oreo and I have the same issue as well. Music over BT was ok on Nougat but after the update, music sounds as if there is digital clipping. And it's there with both my headset and car audio system.
Got the same issue, hope they fix it soon. The only solution seems to do a RUU right now.
Btw. I am on a custom rom (LeeDroid), gonna go full stock and try again.
I would suggest looking in developer options and trying some of the different options for bluetooth in there!
Settings > about > software information > more > then tap the build number till it says you are a developer.
Then
Go to developer options and check under networking, there are some settings to toggle in there.
You may find something you are looking for! I personally haven't tried bt since the update so I don't know if it is a common issue. Good luck!
Thank you!
Thank you very much.
Playing around with the bluetooth options in the developer's menu solved this issue.
The audio quality through bluetooth is now pretty much the same as it was with the previous android os

Share what settings you stuck with so it may help the other people with the same problem
Hey there!
Same problem for me since updating my U11 to Oreo - very poor bluetooth audio quality...
I tried using different bluetooth settings under the developer options but the thing is: no matter what I choose, it keeps switching back to the default values not affecting anything at all.
If it switch back to default SBC it means your headset/BT device doesn't support other codec.

That's not necessarily true. On 7.1 both Bluetooth devices which I use can support either AAC, SBC and aptX. My understanding is this issue occured because of the removal of AVRCP 1.3. I think Google added 1.3 back to Android 8.q because of this.

Yours is not necessarily true either. I'm on 8.0 and I can still use aptX if I want but only if my BT device supports aptX.

I'm not arguing that aptX and other codecs aren't working on 8.0. What I'm saying is that with certain devices, we are no longer seem to be able to use certain codecs that we could use prior. It's obviously device dependent, but to say their isn't a problem and blame it on the Bluetooth device is incorrect. Infact the same problem has occurred on non HTC devices when they've upgraded to 8.0 such as the OnePlus.

Fair enough, I didn't understand.
Does anyone know how to make the bluetooth options under developer options stick? I'm on stock unlocked Oreo, and they go back to defaults as soon as I change them. I've tried changing them whilst connected in the car, but no change. The only thing that could make a difference is that I'm running Pitch Black Substratum theme. Anyone else got them to stick?
In my Audi a3 2015 before oreo i can able to skip the track with entertainment commad and in the display i saw name of the track. After update i have lost all funtionality and the car see my device only like esternal suorce . Can i do something?

Help using a tablet together with a phone in a car

Hello!
I hope getting some help & ideas for a new idea I'm trying to use in my car.
I have an old Volvo, with next to no modern entertainment options, meaning a factory built-in radio (neither DIN nor Double-DIN), with no bluetooth or anything fancy. A good radio with a really good sound and equalizer (DolbySorround), but that's it. And a seperate navigation system with no online connectivity or recent updates what so ever (last update is from 2014 for a nice 300.-€).
My idea would be:
Tablet (in my case a Fire HD8, unlocked, rooted and with LineageOS 14)
Phone (Xiaomi Mi Mix2, as well with LineageOS, but LOS16)
Bluetooth receiver from Aukey (that I can wire in with the equalizer)
So far, so good. But here comes the problem:
I want to do some things on the tablet, like navigation, music streaming and calls. Is it possible, to connect phone and tablet in a way, I could start the music (Amazon, Google and my own Nextcloud) from the tablet, where in reality the phone makes the connection and "sends" the sound to the tablet (and from there the tablet to the BT audio receiver) or directly to the BT audio receiver, as long as I can control that from the tablet. Or the navigation (tablet) can use the internet connection from the phone. And last thing, I want to make or receive calls on the phone, but I would like to control that from the tablet as well.
I think you get the idea, what I'm trying to do here.
I'm really not sure how to start, the hardware is already here, but I'm willing to buy other stuff, as long as it works afterwards.
Any ideas or input is very welcome, I'm a little stuck here. Thanks a lot in advance!
