Thanks for your report. I am sorry that there is some bug since my update, but
I didn't have any means to test it. I will try to have a look at it shortly.

I am sorry to come back to you so late.

However, your backtrace does not seem to be complete. Is it possible for you to
obtain a longer backtrace? I need to know the call sequence within the usb
sound driver.
