    Nigel you hit the nail on the head! I brought up Alsamixer and PCM 
was off. I fixed that and now VLC has good music now!!!

What I have is MASTER PCM IEC958 IEC958 C Docking External Internal.

    I will watch the sound as I re-boot ect. and try to find out why the 
alsamixer got turned off. And I will print this message :-)
