I think I've investigated that assertion already before, but I couldn't
find any bug just by reading the code. At that time I wasn't able to
reproduce it myself, though, but now I am able to do that. It seems that
the 96 kHz sample rate is indeed an important part of the setup, because
without it there's no crash.

I'll investigate this again.
