[SOLVED] Bluetooth has not been working with A2DP but is ok with HFP

zoltix · 2024-05-19 17:38:40

Hello,

I have an issue with Bluetooth. I updated my system with the command yay -Syyuu, and since then, Bluetooth has not been working with A2DP sink (high-quality audio) but is functioning with HFP (low quality). I tried to downgrade the packages with these commands:

sh

sudo pacman -U /var/cache/pacman/pkg/bluez-5.73-4-x86_64.pkg.tar.zst
sudo pacman -U /var/cache/pacman/pkg/bluez-libs-5.73-4-x86_64.pkg.tar.zst
sudo pacman -U /var/cache/pacman/pkg/bluez-utils-5.73-4-x86_64.pkg.tar.zst

but nothing changed. I have no idea how to troubleshoot this issue. Could you help me? Thanks in advance.

* Which packages were updated (/var/log/pacman.log)?
* Can you pass /etc/bluetooth/main.conf?
* Is multipleProfile set to multiple?

In my case sometimes the headset starts in HFP and only after power cycling it (unrelated to any package version AFAIK) it picks the correct profile (Sony WH-1000XM5).

*If the profile switching is set to auto and PA/PW discovers input (microphone), it will switch to the HFP. So check that the microphone does not have any "consumers" (e.g. Zoom, google meet...).
* Try disabling headset profile as in Arch doc.
* Can you try with Pipewire?

zoltix · 2024-05-20 10:59:02

pipewire: I'm afraid of having other problems. Is it stable, and has it become the recommended version for Arch?

impossibleveins23 · 2024-05-20 11:08:03

BT in Linux is no fun. I can only say that PW is constantly developed and works for me (in my exp both PA and PW has suffered from stability and functionality issues) and recently PW is stable enough in my setup but YMMV.

At least we have 2 projects so you have options if one doesn't work for you (may also narrow down the debugging)

You're right, with pipewire, it's working....

impossibleveins23 · 2024-05-20 11:53:49

Great. So now we can assume that the problem is within the Sound Server.
you can try debugging pulseaudio and see if we can spot anything or if you are satisfied with PW as solution, please mark this post as [SOLVED].

zoltix · 2024-05-20 12:43:57

I am satisfied with PW; everything seems to be working properly.
