Sound on Squeeze

[Lisi <lisi.reisz@gmail.com>]

Hello, all!

On a new installation of Squeeze the sound is muted.  I have checked Alsamixer 
and made sure that master and PCM are not muted, as recommended by Claudius.  
But sound is still muted.  

A large part of the problem is that I am a total ignoramus when it comes to 
sound, so although i have launched both Alsamixer and Kmix (consecutively, 
not simultaneously!), I can see nothing wrong.  But as I don't know what to 
look for, (other than, thanks to Claudius, the 00s in Alsamixer for Master 
and PCM), that is not surprising.

Where do I look next?  And for what do I look?

Thanks,
Lisi
