New subject: [linux-audio-user] Playing WAVE, was Re: (no subject)

Quoting Ismael Valladolid Torres &lt;ivalladt(a)punkass.com&gt;om>:

...
  I run the command below and it works, it plays the
wave file:

 $ aplay -D default shared/testing.wav
 Playing WAVE 'shared/testing.wav' : Signed 16 bit Little Endian, Rate
 11025 Hz, Mono

 However the command below fails:

 $ aplay -D hw:0,0 shared/testing.wav
 Playing WAVE 'shared/testing.wav' : Signed 16 bit Little Endian, Rate
 11025 Hz, Mono
 aplay: set_params:901: Channels count non available

 I thought it was posible to select audio channels this way using
 aplay. No .asoundrc here. Any ideas? 
your system probably has a global /etc/asound.conf which maps default to a
plughw device of some sort. That way alsa converts the mono 11025hz signal
to something your soundcard is capable of playing.

With hw:x,y you can select the hardware (hw) device (x) and subdevice (y).

It depends on your configuration which number each device has, and it
depends on your hardware what subdevices each device has. Subdevices are
_not_ channels.
