Does the soundcard have support for the format of the soundfiles?
(stereo 44100Hz). If it has more than stereo out it will probably not
allow playing of 2 channel data directly, and the same if it's fixed to
48 kHz it won't accept 44.1. Try using 'plughw:0,0' as device instead,
it will make ALSA do the proper conversion.
