On the Game Theater XP card the amplifier is always turned on (with the exception when unmute the CD volume).

The Game Theater XP got two cs4294 codecs. That's why many mixer control are duplicated, and probably some of them may be obsolete. Like microphone and headphone on the secondary codecs are not wired to anything. >Also I tried the SPDIF in with this new DSP code, and it doesn't seem to >work.

Look on the back on your beutiful blue break-out box and you will find them -;) /Benny ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
