Is there a patch for C-Media CMI9739 AC97 with snd_ich module to make the volume mixer work?

[Tom Norris]

Hey everyone,

I noticed xmms was either going mute or full blast when I came across 
this: 
http://lists.freebsd.org/pipermail/freebsd-questions/2004-October/062858.html 
thanks to google.  I was just wondering if there are any patches to make 
the mixer work?  Or, if there isn't, where would I go to get into on how 
to do it myself?

Thanks a bunch,
Tom
