Still not crashed, your new usb stack seems stable now with snd_uaudio !
Thank you very much for that.

Aside, I do confirm that I was able to either use 2 or 6 channels with =
the
former driver. My "upper" sound layer (pulseaudio) was formerly able to
start with either 2 or 6 channels using /dev/dsp. Now it crashes if I
specify 6 channels.

It is a little regression, I do not know if it can be addressed easily.

Best Regards,

Laurent H.
