Pauli,
Thanks for testing! What userspace software did you use? Pulseaudio at
least I think had assumption that mtu <= 60, which breaks here
(Pipewire works, don't know about bluez-alsa). If otherwise, maybe it
then needs also the manufacturer flag.
I am using Pipewire 0.3.32.
When I wrote "this adapter (...) reports an SCO MTU of 96 bytes" in my
previous message, I meant that this was the value present in
hdev->sco_mtu around the problematic code location. If this was the
wrong thing to take a look at, please let me know.
