 - ioctl(..., SNDCTL_DSP_CHANNELS, &nchannels) for not supported nchannels does not
   return an error and instead set nchannels to the default value. Instead of
-  failing with no audio, fallback to stereo or mono.
-  Fallback logic inspired by `OSS v3 Programmer's guide', p. 34.
+  failing with no audio, fallbacks to stereo.
