    Hi Daniel, I meant to say that for example, my sound was fixed by 
turning the PCM control back on. Nigel talked about a FRONT control that 
I do not have on either of my computers.

    I have re-booted my laptop 3 times and the re-boot has not changed 
the AlsaMixer settings. But something did of course, and it would be 
interesting to know what.

    Be interesting to see how many of the Intrepid sound problems turn 
out to be something other than a AlsaMixer adjustment. My guess is not many.
