In that case, make sure you having CONFIG_SND_DEBUG=y at least. CONFIG_SND_DEBUG_VERBOSE=y would give you more, but not mandatory as sbxfi.c doesn't use snd_printdd() much. > > Also, run with debug=2.

I guess it's a timer issue.

Yes, this seems explaining the symptom (but not the cause :) thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
