Thank you for the report. This panic certainly shouldn't happen, but I assume that it won't be properly fixable until we get around to upgrading to the newest librespot version.

Anyway, regarding your specific problem, something funky is going wrong with your ALSA setup. You could try specifying values like device (see aplay -L to see possible values). Another option would be to try another audio server like pulseaudio?

Hope this helps!
