seems that we are using amixer to control the volume settings in a
rather hackish manner. The easiest (hack) workaround would be to comment
out line 98 and 99. This will disable volume control.

    def get_volume(self, chan_id):                                        
        amix_ostream = os.popen("%s  cget numid=%d" %(ALSA_AMIXER, chan_id))
        # ToDo - parse everything!                            
        amix_out = amix_ostream.readline()
        amix_out = amix_ostream.readline()
        amix_out = amix_ostream.readline()
   ##     if amix_out.find("value") >= 0: 
   ##         return int(amix_out.split('=')[1])
        return 0; 

A better alternative would be to push for python-alsa into OM.

As a temporary workaround, use alsamixer once sound module has been
disabled from settings app.

  $ alsamixer
