Hi guys
I did exactly the same steps that Mariano did. My system is a Ubuntu based distro, 64 bits.
I ssh the emulator with nemo user, thats the trick. It seems that in some systems the master channel is muted by default, wich causes this problem.
All the best
João

Ciao Mariano
The key bit is the user nemo.
I was trying to start alsamixer as user root, and got "connection refused".
After connecting via ssh as user nemo alsamixer works!
1000 grazie
Chris
