Thanks again Fausto,
I really appreciate your help.
I can see how your code works, and also it should be possible to do the
exact same thing with amixer. However I have noticed that I can only control
some of the "simple mixer controls" in a mixer but not all of them. It
appears I can control the simple mixer controls that have "volume"
capability, but I cannot control simple mixer controls with the pvolume,
pswitch, cvolume, cswitch etc.
The command I use is this: amixer -c 0 cset name='Ext Mic Boost' 0
but if I try
amixer -c 0 cset name='Capture' 1
I get the following error
amixer: Cannot find the given element from control hw:0
I have attached the also-info.txt for my machine to this mail.
Thanks
Erumusele
