sound card and win 7 sleep mode

[Seasidepeter]

I've finally managed to track down the reason my Win7 won't
automatically go into sleep mode: it's the sound card. ANY sound card.

I've tested exhaustively, switching between onboard (via) and two
different other cards, one soundblaster internal, one usb external. When
the soundcard- any of them - is disabled, windows goes properly to
sleep. When it's enabled, only the monitor goes off.

What the hell is that all about?
Any ideas what might cure it?

I don't have a useful answer, but I have to ask..."sound card"?? I see
a lot of systems of varying age come through the shop, but I can't
remember the last time I saw a system with a discrete sound card. What
a flashback to the 90's.

Anyway, I hope you get it sorted out. I have a feeling the sound card
is using interrupt registers that aren't 7-friendly. (I just made that
up.)

Check to see if any of them are trying to access the web for updates. That
may be the problem.

Some of us use discrete sound cards so that we will have a toslink
optical spdif INPUT. Those of us that wish to record music from high
quality sources such as digital satellite or cable receivers prefer an
optical input. There are only a few motherboards like the Intel P55
that still have optical inputs, especially since ABIT left the
motherboard market.

Thanks...I've disabled the Creative update service, but still no luck.
I'll keep googling.

Yes, it's probably something obscure like interrupts...beyond me, anyway.
As to why a soundcard - I'm a classical music fan, and get much better
quality playback through my Xonar than through the onboard sound. Sadly,
the pc won't sleep with the Xonar in either....
