subsystem in favor of Cvars. These new cvars are:
 o  snd_device  defaults to "" which selects the default device of the system
    (eg, plug:0,0 for ALSA 0.9 or /dev/dsp for OSS)
 o  snd_rate    defaults to 0 which selects the system default rate.
 o  snd_bits    defaults to 0 which selects the system default bit depth.
 o  snd_stereo  defaults to 1 (0 is mono)
