I've got a Hercules Game Theater XP,what's known for moment is that:
EGPIO0 selects the SPDIF input,
the EPGIO2 turn on the Amplifier, and that's implemented in the current
driver.
With the Game Theater XP, the Amplifier is turned on all the time, with
the exception if you unmute
the CD in the mixer, (this is for all cs46xx cards). Dont known why
it's done in this way, probably with
a good reason in mind, i've just complained about that piece of, not
touched it (yet).
If the sound card amplifier is turned off for some reason the sound
gets somewhat lower, bad and distorcionated,
about the "flat bass", I have not experienced that. I daily use the
HeadPhones, and I got my the SPDIF
output connected to the receiver. To activate the SPDIF it should only
be to unmute the "IEC 958 Output" in
the mixer, no GPIO's are involved on the Game Theater card.
About the SPDIF output the analog parts of the soundcard should not
matter at all, it's like whatever what you playback
will be sent directly "as it is sampled" to the SPDIF output, it's up to
the Stereo reciever (or whatever you got ...) to do the DAC stuff.
