After checking out the whiki digital howto site I figure that since you can resample you should able to change the volume. Sadly the site is sound blaster specific.

I don't have to mess with the amp. The driver probably just changes the amplitude before converting it to a digital stream out the SPDIF. - James _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
