Hi,
I've already posted about part of the problem in an existing thread, but the more I try to fix it, the more weird stuff happens.
I am unable to get call audio to play through the pi, when Bluetooth is selected as the output for the call I get no audio, but microphone input seems to work fine. What has started happening now is that after trying to make a call or anytime I use the head unit server option to connect wirelessly, my audio quality goes down the drain and there is a crackling noise coming through the the speakers as well. This will stop if I disconnect and reconnect the phone via USB. I have tried with different USB ports which does not seem to help the issue. Bluetooth adapter seems to be working as intended and the sound card does not have this issue until I attempt to make a call. For reference, I have included the parts I am using below:
- OpenAuto ProBeta 3.3.2 on a Raspberry Pi 4 2GB
- Waveshare 7" screen ( c )
- CSR 4.0 adapter (btswitch external command executed)
- Ugreen in/out stereo sound card
- Pixel 2 XL on Android Q Beta 5 and all Bluetooth permissions given to OpenAuto Pro (There may be an issue with the Q beta and Android Auto on the phone end, I will do a clean install of Android Pie later tonight).
- USB microphone (for testing purposes, will switch to a 3.5mm stereo microphone when it arrives).
Thanks in advanced for any advice you can offer.
