I am urgently need "Mic Bias" widget, I see it's declaration in sound/soc/codecs/sgtl5000.c, but I don't see it in alsamixer. Should I? If not, where can I change it's value in userspace? I use kernel 3.10.
Why do you need to frob with the bias ? Try this patch Advanced Linux Sound System development instead, it might help with your problem as it will toggle the Mic Bias correctly afterwards IIRC.
