How to unmute a record channel & check if it is muted.

[Alain De Vos]

Recording is muted by default. By clicking in xfce4-mixer it is easily fixed.
How can I unmute manually , in a script and/or check the muted status ?
Running the program "mixer" does not show any usefull in this context only recording volume levels but these are ok.
Maybe I must hint ?

I mute by setting volume to zero. I'd like to know if there's another way to do this.

I have the impression the card is badly initialised and setting volume explicitly solves it.
