Check on the audio settings what codec is actually in use? I have the XM5. I haven't used bazzite specifically, but on the steam deck they work well (for playback only, I don't play online). On KDE they work well for zoom calls. On some occasion they might connect... Wrong, using the most basic Bluetooth profile. And then they do sound like ass. Restarting Bluetooth usually fixes it, if reconnecting is not enough.
What was happening was the codec was dropping back to mono in order for enough bluetooth bandwidth to also transmit the mic. I don't think there was a way around it, it's a pure hardware limitation at this point. I could manually change the codec to a high quality option but it'd kill of the mic. I've ordered a new headset with dedicated 2.4ghz dongle. Thanks for your help.
That sounds like...a hardware issue. Maybe the antenna is broken? Any normal codec would work up to a certain distance of several meters. Unless the antenna is being blocked.
There's five codec options. I'll have a tinker and see if I can get a better one going. Thanks for the input.
SBC / SBC-XQ / AAC / CVSD / mSBC
The first three are listed as High Fidelity Playback A2DP link. The last two are Headset head unit HSP/HFP.
LDAC is the highest quality codec you can use on those. I'm not sure if you can do a microphone profile with it. Search your distro's package manager for ldac and it should give you a package to add it.
Thanks, I'll see if I can work it out for Bazzite.
FYI, SBC-XQ should be functionally just as good as LDAC and doesn't require nearly as much fiddling because it's an open standard.
Thanks. That's what I've been using. I played with the codecs with friends on discord giving feedback.
And you have to disable the two device connection setting on the headphones to use the LDAC codec on them. That threw me for a loop on mine for a bit when I was trying to get it enabled.
