[SOLVED] Weird bluetooth problem...

Honestly, this is my first time installing Arch without the archinstall script. I'm always afraid, if anything breaks, I'm screwed. But when I installed using the script, I didn't get this problem, until now:

Bluetooth works like it should work, until I get into a Discord voice chat (both browser and native application), my audio quality gets worse and I can hear others in the chat, talk with them with no problem. Same for other OSes too (win, android, even other distros like void, alpine, debian, etc). But when I get out of the voice chat, the audio suddenly stops. NOTHING can be heard then, no music, no system sounds, no nothing. Or sometimes it continues to play with that garbage sound quality. This fixes only if I disconnect my earphones and reconnect them. This problem was not present when I used the script to install my system. But now, this bothers me a lot, sometimes I have to restart bluetooth from systemd, even that fails sometimes, inevitably requiring a reboot to work again.

I use KDE (latest).

Here is my installed packages:

bluez
bluez-libs
bluez-qt
bluez-tools
bluez-utils
gst-plugin-pipewire
kpipewire
libpipewire
pipewire
pipewire-alsa
pipewire-audio
pipewire-jack
pipewire-pulse
pipewire-session-manager
wireplumber
bluedevil (Interesting fact: bluedevil was working without pipewire installed! pulseaudio isn't installed either)

Just 2 pulseaudio-related packages:

plasma-pa
pulseaudio-qt

And sorry for my bad English...!

Re: [SOLVED] Weird bluetooth problem...

The sound degradation is normal for BT because you have to switch to a headset protocol from a "high quality" audio setup. That it refuses to play audio or switching back to a higher quality profile when no recording is taking place anymore sounds like a wireplumber/pipewire bug, the latter of which had a bigger update a few days ago.

When things aren't working what are your outputs for

pactl list cards
pactl list sinks
journalctl -b --user-unit pipewire --user-unit wireplumber --user-unit pipewire-pulseaudio -u bluetooth

post these wrapped in  [code][/code] tags.

It's highly unlikely that KDE - or the fact you didn't use archinstall - has any bearing on this. Another always likely candidate is a kernel/bluez regression but let's see those outputs first

Re: [SOLVED] Weird bluetooth problem...

This is while things aren't working yes? Does the switch back just select the wrong default? Can you force a manual switch with

pactl set-card-profile bluez_card.84_AC_60_21_28_AA a2dp-sink

Re: [SOLVED] Weird bluetooth problem...

It switches to a2dp-sink, but still no sound can be heard.

I did it after it became crappy sound again. But then no sound can be heard.

But the only setting that works is: HSP/HFP, codec mSBC (Changed through plasma-pa graphically)

Re: [SOLVED] Weird bluetooth problem...

Hey, it fixed after I upgraded Arch. Seems like it was an issue with gstreamer. Happy now!

FIXED

Thanks for the help, btw!
