Try .. mad ! audioconvert ! alsasink or .. mad ! audioscale ! alsasink or
.. mad ! alsasink device=plughw:0

The first solves soundcard issues if it doesn't support 'any' setup
concerning bitdepth, channels and the like. The second does this for
samplerate. The third lets alsalib figure out device emulation by itself.
