[Debian] Volume very low

[Michele Renda]

Hello,

I am using an application that use FSO Framework to make call.
It run well, but I have a stupid problem.
When I do a call I listen the other person with a low volume while the 
other person listen perfect to me.
I tryed with alsamixer to put all the level to max, but no result.
Someone has some tips to appy to a just installed Debian at FR?

Thank you
Michele Renda
