Bluetooth Headset with Mic Not Working

Ask Fedora
1

Hi,

The output of my headphones work fine if I enable output only - but when I turn on my mic like in the image provided, it only leaves the microphone on and I can only hear myself through it. I get no output anymore from the Output device. It’s a single headset, yet they can’t work at the same time.

Further, it doesn’t even look like Fedora is picking up my input.

at the moment i’ve work on the same issue. on my table i’ve oneplus bullets 2 and jabra elite 75t, both devices working fine aptx-hd sounds great for bt audio. but the mic will not recording anything only in the worst mono mode. the bluetooth device is a Intel ax200 chipset with bluetooth 5.1

Hi, the first step should be a system upgrade, Fedora 30 hasn’t been receiving updates since May 2020.
After upgrade to Fedora 33 we’ll know whether it’s already been fixed, or require further troubleshooting.
