Hi,
i've got a problem after vista update on my xl202. i can't listen 5.1 and dts sounds with sigmatel audio device.
i try to uninstall and reinstall the sigmatel drivers but the sound is already stereo 2ch.

thank you.

Hi

I'm having the same problem, did you ever get it resolved?

Cheers

I presume you have already gone into Control Panel and set the audio out for 5.1 and AC3?

Hi guys
Which Sigmatel driver do you use ? I've tryed different driver version because the original one generate an error on control panel sound reality audio. But with other drivers I loose the advanced tab for setting HDMI audio output.

Plus, I've Vista with Nvidia 158.18 driver version.

I can't listen audio from my device. See my post here a couple of day ago.

thanks
Davide
