[Alsa-user] What are controls on Alsa Mixer

[Brett I. H. <bre...@be...>]

I am running a Turtle Beach Santa Cruz card under Gentoo Linux.

Is there any documentation or information that explains what the names are on 
the alsa mixer.  Some are obvious but the IEC and others are not.  According 
to alsamixer my card has a lot of features but I don't have a clue to what 
they do and I'm also trying to troubleshoot a problem (I have to unmute the 
external every time I reboot to get sound to play and I don't remember having 
to do that in the past).  The TB docs aren't much help and I've browsed the 
kernel docs and looked at the CS46xx driver info but there isn't anything 
there about it.  I also checked the archives of the user and dev mail list 
but didn't find anything.

Please point me in the right direction.

Thanks.
