Audio distorting and cutting out

Hello,

I've been a Vegas user for years. I've never had any issues with Vegas before.

I recently upgraded to 8.01c on my new Intel Quadcore.

My audio is dropping out and distorting in Vegas when video is playing. Without video (or when I use Sound Forge) the audio is great.

I thought the problem was because I was using onboard sound. I bought a dedicated sound card but that didn't solve the problem.

I considered that the graphics card may be the culprit so I updated the drivers on it. It's a geforce 9800 GTX. That should be plentry of horsepower.

I'm running Windows XP SP2. I built the machine (as I did all my prior machines) so it's got no extra software running.

I've searched the net and this forum, but no answers. I'm pulling my hair out here. Any ideas?

8.1 is for 64 bit OS. 8.0c is for standard 32 bit OS. Which OS do you have and which version of vegas are you running?
If that's all straight you need to look at your audio driver and buffer settings.

I'll look into the audio buffer settings. Thanks for that suggestion.

Vegas seems to like ASIO drivers. If your soundcard (or motherboard) manufacturer doesn't have a decent driver you can always try ASIO4all which is a free driver that lots of folks here speak highly of.

I tried the Asio4All drivers, wiping off the old onboard audio drivers, wiping and reinstalling the Nvidia card drivers, etc. I checked the drive settings, mobo drivers etc.

Nothing has helped. Audio is rock solid in Sound Forge, but sounds terrible in Vegas.

This is the strangest problem. My machine is very vanilla. It's an Intel 975x Quadcore board with a 9800 GT card. I have nothing else in the machine, no games or anything

Briody:

Please fill out your system specs and make sure to expose them in your profile.

What audio hardware are you using? You mention you purchased an second audio card. What kind?

I have found it one has another soundcard with a digital input enabled (with or without SPDIF signal being received), it can affect other soundcards atached to the XP audio subsystem. Not sure if that is a weakness in XP or the other soundcard driver....
