Comment (by cehoyos):

 Replying to [comment:7 burek]:
 > Also, notice the ALSA inputs are always at 48000 Hz, but I've
 specifically added "-f alsa -ar 44100 -i ...". Should I report that as a
 bug too?

 I suspect the sample rate is a hardware property, also see the
 documentation of snd_pcm_hw_params_set_rate_near() (that sets/gets the
 sample rate).
