Hi. Whenever I turn on my wireless headphones, they autoconnect to my computer, but the sound is pitch shifted down. I think it must be something like a mismatched sampling rate, as increasing pitch 48k/44,1k=~9% sounds normal. After disconnecting and reconnecting manually, the pitch is corrected. I would open an issue in the relevant project, but I don’t know how to debug and find the underlying issue for this. I’m running Silverblue.
You should probably report this to the pipewire project or bluez.
