Re: [Alsa-user] Hercules Theater XP 6.1 and surround

[Benny Sjostrand]

I'd like to be able to use the surround40 with my cs46xx card. Where can
I get the latest Alsa libs?

If you want to live at the bleeding edge then checkout latest ALSA CVS sources, read instructions at http://sourceforge.net/cvs/?group_id=27464

Maybe just copying the CS46xx.conf file to /usr/share/alsa/cards (or /usr/local/share/alsa/cards depending on your installation) could make surround40 work.
