The sequence of driver callbacks issued on a stream start is
.open()
.hw_params()
.prepare()
.trigger()
If the ALSA part really causes this issue, the bad things happen either
in any of the driver callback functions or in the core underneath.
The patch I sent returns an error from the hw_params callback, and as
you still see the problem, that means that the crash happens before any
of the USB audio streaming really starts.
Could you try and return -EINVAL from snd_usb_capture_open() please?
If anyone has a better idea on how to debug this, please chime in.
