Bluetooth phonecalls (2 way audio)

Last week 2-way-audio, simply worked. After an update last week it stopped working specifically for phone calls. I can still play high quality audio and record sound through my desktop microphone to my phone through apps (like Telegram & Whatsapp). Howevery, when I make a 4G phone call, the audio is not passed along anymore. I have the suspicion there’s an issue with the way how pipewire handles that particular signal.

I have no idea where I should start to look to solve this problem, since it just worked last week, and now … half?

Reboot into an older kernel and see if it changes something.

Hi, thank you for helping. I tried booting under the 2 previous kernel versions that where still available in GRUB.

Unfortunately, it still didn’t work.
