No audio output through bluetooth headphones (OnePlus Buds Z)

I was using Garuda Linux about 2 months ago when I had a problem with my bluetooth earphones autoconnecting and disconnecting immediately. It wasn't resolved, so I decided to try out other Linux distros, and I experienced the same problem in Ubuntu and every other distro I tried.

I recently started using Garuda Linux again, but this time, I noticed a different problem. When I pair my earphones, they no longer have the autoconnect problems, and as an added bonus, the HSP/HFP profile also works now, which is absolutely amazing. But the problem is that there is absolutely no audio output when I select the profile as A2DP. Can someone help me with this? I'm using pipewire.

Output of inxi -Fxxxza is below.

I tried the linux-lts kernel, the linux kernel and the default linux-zen kernel, but none of them seemed to fix the issue. The audio output in the HSP/HFP profile works really well, but the quality isn't really that good, which is what is expected. I need the A2DP profile audio, as its much higher quality, and makes music enjoyable. HSP/HFP straight up ruins the quality, but I'm pleasantly surprised to see it work. Can someone help me fix the audio output on the A2DP profile please? I will not be active right now, its 11 pm at the time of posting, so I'll be gone for a while before I can reply to any solutions. Any help is appreciated. (I am using the blackarch version of Garuda Linux, the Dr46onized edition)

I think we move to unsupported software. Why you post in Qtile?

Seems your hardware is not in the kernel?

Check this troubleshooting article.

Also, you may try with pavucontrol (install it if it's not already).


I tried switching with Pavucontrol too, but even that didn't work.

I couldn't get it working after creating the udev rule as per the script mentioned in the article you linked. Although I did find something interesting. Is this related?

It says that Sink #78 State is SUSPENDED. Does that have something to do with this?

Also, thank you for quick reply

Oh GOD. I thought I had posted in Network Assistance. Terribly sorry.
