Call audio only works via bluetooth, with a few strange exceptions - General Questions and Answers

Hi. I'm having a very strange issue. I'm using Blackview's BV9100, a fairly generic MediaTek-based Chinese rugged phone, on Straight Talk Wireless (AT&T network). I flashed an Android 11 generic system image (pphusson's "pph-Treble"), and everything works great, EXCEPT: When making or receiving calls, there is no audio unless I connect a bluetooth audio device. Call audio works fine through a bluetooth audio device (though I get a pretty intense echo of my own voice), and if I then disconnect the device during a call, the call audio will come through the phone's speakers completely like normal. Audio calls and media playback work in other apps, just not Phone. Does this sound like a familiar issue to anyone? Its really weirdly specific and hard to Google, especially with my weird combo of phone and software.
Phone call audio will also play correctly through the phone's speakers when the phone is connected to a bluetooth device which does not support call audio, like my Amazon Echo. Also, I had to factory reset today, and received a phone call before restoring my backup, and this phone call functioned completely like normal, no weird bluetooth workarounds required. I tried withdrawing permissions to access phone calls from apps that don't need it, but no go.
Any ideas?

Howto AutoUse BT Pair for Media Audio?

I've touched on this question before but I may have been using some wrong terminology.
On my S3 I have successfully created a BT pairing with a BT Audio Device use which has a steroe out fed into my car's head unit's Aux In.
So, it is Auto-Paired. That is, when I step into my car and turn on the ignition thus powering up the BT Audio Device the paring is available to be used for Media Audio.
However, in order for my phone to route audio to the BT Audio Device I must enter the phone's BT menu and tell the phone to connect to the Device for Media Audio.
I can either do this through the notification pane to see pairings then tap the pairing to use for Media Audio or I can go through settings->BT and do the same thing.
Either way, it's a huge PITA to do this every single time I get into my car.
There has got to be a way to have the phone automatically route Media Audio through this BT Audio Device upon detection. My previous two phones had nowhere near the ability of my S3 but they had no issues whatsoever with automatically pairing and routing audio to this BT Audio Device.
Is the S3 really this stunted in the BT department? If so, is there an app that fixes this stupidity with grace and non-intrusiveness?

I feel ya, in the past, all I had to do was toggle BT on and go, now there's two or three extra steps which almost defeats the use of a toggle.
I just started searching for some answers and am honestly surprised no one else has made a big deal about this. If I find something, I'll post it up... For now, going to take a look at some system files and build.prop stuff, but it's not really my department.
Got some NFC tags and NFC Task Launcher hoping I could circumvent the BS with a hardware hack. But no, the best this does is auto toggle the BT radio and open the device selection screen where 2 more taps are required to actually use the device for media audio. Any new insight out there? Considering Tasker app but it is rather expensive and no free version to see if it does the trick.
My Bluetooth Auto Corrects Just fine to my cars Bluetooth... Toggle on and go. Running AOKP currently but it worked properly on stock, stock rooted, and Synergy as well.
I haven't gotten a chance to try this yet but I probably will tomorrow.
Tasker forum post indicating the problem is well known, prevalent and hardly any fixes exist:
https://groups.google.com/forum/?fromgroups=#!searchin/tasker/bluetooth$20audio/tasker/TLsjT9Exle8/ZLlgvEn5vUUJ
An app that forces the connection amongst other things:
https://play.google.com/store/apps/details?id=a2dp.Vol
A Tasker plugin leveraging the force connect code which happens to be GPL'd in case any of our fine developers would like to start making ROMs that address this major drawback of using a S3:

I haven't had any trouble with bluetooth devices reconnecting to my phone as soon as I power them on. I'm running cyanogenmod 10 rom.
Also you can get free trial of tasker from here tasker.dinglisch.net/download.html

It seems the issue may be primarily with BT Audio Gateways. I don't have this issue with my laptop at all and I'm imagining car head units rarely see this problem.
That said A2DP Volume App fixed this issue for me. Once configured I did have to manually set the device to use media audio one last time before A2DP Volume started doing it for me. I configured NFC Task Launcher to kill wifi, enable BT and launch A2DP volume when it contacts the tag in my car and it works perfectly. Since NFC Task Launcher front ends into Tasker and Tasker has the A2DP force connect plugin available I'm seriously considering getting Tasker for all the other cool features it can do besides scratching this particular itch.

You can fix this relatively easy by getting the app Tasker. I use it to do things like automatically start the music player I want when headphones are plugged in, to turning up the brightness automatically when I am getting an incoming call, etc. I am fairly certain you could set up the program to do whatever you want via bluetooth if you fiddle with it.
Gluck!

LOL, if you had only read the rest of the thread...
Yeah, Tasker cannot do this OTB but with the A2DP Connect Plugin it can. Or you can just run the A2DP Volume app and do the same for free.
That the A2DP Connect code is GPL it would be super sweet if our developers incorporated the magic into the ROMs so that a base install didn't need apps to do something so simple as automatically route media audio to BT gateways.
This happens to me when I use the wrong settings in my cars head unit. My Toyota gives me the option to pair as a multimedia device, a phone or both. If you set it up as just a multimedia device then you won't have some functionality. Check your head unit manual and try to re-pair. You might have to delete the existing pairing for it to work right.

Yeah, it's not a head unit, it's an audio gateway that basically is just a BT receiver with a stereo out and no interface so it is what it is with no configuration options. This issue with the S3 appears to be primarily related to these types of devices.

Oh okay. When I look under the bluetooth menu in CM10 I have a paired connection that I named Car Multi-Media and if I look at its settings I see profiles called Phone audio and Media audio. I'm guessing you just have a Media audio profile. Not sure how to help you there. Sorry.

bluetooth no call audio pixel

I used to be able to hear calls and media whilst connected to bluetooth in my car. one day it just stopped working. media still works but when i make a call or receive one, there's no audio. calls ,audio, and contacts are all checked in bluetooth settings. i've forgotten devices, rebooted, reconnecting, and nothing helps.
bluetooth connects to everything fine, but no call sound over any accessory i try. got a new car and it won't work in there either. i'm on android 7.1.2 .
searched all over and plenty of people are having these issues but none of the posts i've read solve my problem. any help would be appreciated
Hey hey, I have a 128GB pixel with the same issue. I actually opened a case with Google support today about it. about 3 months back, only phone audio stopped working in my car. I was hoping the 8.0 update would fix it but it did not. I have a 2017 Honda Civic LX. I tried everything on my phone - even factory reset. Media audio works, I can play Spotify just fine but when i get a call, I can not hear the other person and they cannot hear me. The phone indicates it is connected via bluethooth... I'll try to update this post with what they find.

128G pixel here. This happens with every Bluetooth device I connect it to. 2 car stereos, 2 speakers, and a headset. All worked fine and suddenly one day... Didn't. I was hoping O Would fix it with all the Bluetooth bug fixes and changes they implemented.

Darn, so the issue is a bit different. Mine works fine on a couple of other speakers I have.
Did anyone ever solve this? I've got the same issue, but it effects *all* my Bluetooth devices, but only when I am switched to my secondary user profile.
I've reset the phone app but no dice.
My phone will say it is connected to the Bluetooth device for the phone call. If I switch to speaker or phone and then back to Bluetooth, it works. Anyone else have similar?

Hi!
After hours of Googling you are the first I found who has the same error.
I have a Lenovo TAB4 8+, my kid wants to use Zoom and his Bluetooth headset but only the speaker and mic on the tablet works. I tried fresh install, without luck:
There are 4 type of users:
- Owner (primary - this is the only profile which works for calls on bluetooth headset)
- Standard Users (secondary - bt headset only supports listening: Spotify etc..)
- Child (bt headset only supports listening: Spotify etc..)
- Guest
The bluetooth headset is working with other devices, but not with this one. Unfortunately I have no other android device which supports multi-user.
Moreover, there was an hour when bt call worked from secondary user, but couldn't find out what is the problem.
Can anybody help me on this?
Best regards,
Karoly

Bluetooth and microphone issue on latest 9.0.2

Hey guys,
the OP6 is one of the best phones I had yet even with the stock os. But even before returning to stock I used Havoc OS. There, I didn't have any problems that couldn't be fixed in the settings. Now when I have a bluetooth headphone connected I have this short crack every 5 to 30 seconds. I tried adjusting all the settings in the bluetooth section but non works. Since it worked in havoc OS I figured it must be something software related. Same with the mic. It works flawlessly on calls but upon sending a whatsapp voice message it's very quiet it sound like it was adjusting the sensitive very quickly up and down during the recording, producing a weird sounding message.
Do you have any suggestions how to fix this? Maybe something inside the build.prop or audio related xml files in system/etc?

bluetooth device drops in browser based group video chat

So I've been using tinychat via chrome app on my galaxy s20 with stock android 12- basically a group video chat based site, and I've been connected via bluetooth earbuds flawlessly for months. I'm not sure what happened, but now whenever I attempt to cam up on the site, the audio and mic function on my bluetooth device drop out, and defaults to the phone's audio speakerphone and mic. I also no longer see bluetooth audio as an option for the site's input/output devices. I've tried looking in the chrome settings for specific options, but nothing helped. Does the same thing on samsung internet app and opera, so I'm thinking it's a persmissions kind of issue.
Not sure what I did, but I may have clicked on a prompt that might have messed up the previous configuration. I've searched throughout google without much help, so hear I am!.
bump!

Hearing Aids: making calls

Hi,
anybody outhere with hearing aids who can make calls with their hearing aids as audio output and a working microphone?
If so, could you please state what
- hearing aids
- phone
- OS version
- and if you had to do something else (install an app, add a setting, ...)
?
Thanks!
I recently got myself a OnePlus 9 Pro and after pairing my Starkey HAs the phone outputs all audio to the HAs w/o trouble, even in a call -- but there's no microphone, hence in a call I hear the other party but they cannot hear me.
While the HAs are recognized as such, Accessibilty does not offer a setting for HA compatibilty, nor is there a way to pick the audio input device or at least check/modify the microphone volume.
All info I can find seems outdated or misses the point entirely (using HAs to make a call).
To answer my own question: w/ OOS 13.1 sound is routed directly to my hearing aids and one of the phone's built-in microphones picks up my voice (need to experiment further to find out how to hold the phone to get the best quality).
I currently try to figure out if it still works that way if I flash LOS ...
