I have been struggling with this from quite some time.
When I double booted my laptop to Ubuntu 22.04. It worked fine. Today, I had a call and I remembered the Ubuntu doesn't work with Bluetooth Earphones as Mic out-of-the-box, so I followed the followingMy microphone is not working
Install "Jack retasking for HDA Intel sound cards" with:
sudo apt install alsa-tools-gui Open it with ⊞ Win or in terminal:
hdajackretask Select the up-right checkbox "Show unconnected pins"
In the not connected pins 0x18 and 0x19, select "override", and select"microphone". If, they don't have the microphone option, do this in0x16 or 0x12
Click "apply now" (bottom right) and "install boot override".
install pavucontrol
sudo apt install pavucontrol Open pavucontrol, go to Input devices(4th menu) and select "Microphone", instead of "Internal microphone"(if it appears "(unplugged)" see if the volume indicator moves whileyou speak, otherwise restart - it can still be "unplugged" but shouldwork).
For dual-boot systems, turn off the machine after the last windowsuse.
This solution had worked for me for a different computer but it didn't for this.I've been trying a lot of things but it just doesn't work.
I do get the following in syslog
Nov 9 20:26:54 kungf bluetoothd[527]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 04:CB:88:D0:F4:9A: Protocol not available
