uaudio.c: Obvious mistake that need to be fixed.

feeder_volume.c: Ok, looks good. My concern is endianess issue, but
                 this can be ignored for now. I need to examine it
                 first.

channel.c: Changes against feeder building process is a bit sensitive,
           some brute testing need to be done here.


Thanks.
