Same problem here. I have modified the initialisation script to do
this each time alsa is started. Moreover, since alsa seems to be
unable to sleep, I have done more modifications to unload alsa and to
be sure that it doesn't reload itself automagically (because of xmms
which is always querying the mixer).

However, the mixer is still no consistent : the volume is not keep
when plugging and unplugging the headphone.
