Crashing/Stuttering with games on Xonar

[VanishingNerd]

On trying to play Oblivion, while keeping the D3D option on, the game simply crashes. The load bar reaches the end and then the "Windows is closing Oblivion" message appears.

For Assassin's Creed, the voices stutters a lot. Every time a new voice sequence starts the voices stutter.

Both these problems disappear if I turn off D3D, but then the sound reverts to 2 channels instead of 5.1

I have the latest drivers for all the hardware(audio, video, chipset, etc) including the latest BIOS for the motherboard.

I have the following PC configuration.

E8400 OC to 4GHz
Abit IP35-Pro
EVGA 8800GTS 320MB
Logitech Z-5300

I have Windows Vista Ultimate 64-bit. I bought this card mainly for its good Vista x64 support.

How can I fix this and get surround sound in games?:S

I'd say mail support. very few have the card :ashamed:

a comment on newegg says a clean vista reinstall cleared up things

 

[VanishingNerd]

Yeah I am planning to do that when I get back home from the office, but I was hopping some one had some idea about this.

Sent a mail to Asus. Lets see what they have to say.

I so wanted to do a review on this.

isnt xonat do all that eax stuff in sotware mode? maybe driver issue?

 

[VanishingNerd]

That is what I am thinking. Probably because of SP1.

Do post any updates on the issue as I'm getting a Xonar myself.

^What mode have you set the card in? I've used the DS3D GX2.0 mode successfully.. used WiC, Cryshit and UT3. No issues.
