Vista and power options - Audio out of sync

Hi folks, I'm using a USB tuner (Avermedia Volar x). It is compatible with
Vista x64 (I'm using Ult)

The tuner works fine, the tuner program works in Vista x64, channels are
tuned in, and I can watch TV

However, I've just noticed, that if I leave power options on balanced (the
default), the audio is fine.

But, if I change it to power saver, the audio (when I watch TV on the tuner)
goes out of sync.

I tried changing USB settings to disabled (under advanced power settings
(under power saver), no change the audio is still out of sync.

Any ideas on WHY it only goes out of sync, if I change it to power saver?

Any ibfo appreciated

Thanks. System is up to date, and everything else works fine

At a guess, the slower CPU speed that power saver modes activate are not up
to the task of handling the data stream.

When you put it on power saver your CPU could be running at 600 mhz. The CPU
is slowed down to save power.

Hmm thats a good point, since the CPU supports speedstep. So it'll go down
in speed (normally)
when I'm not doing anything / the system is idle
