Hey new release and new problems. When I first installed the beta 32 bit version of windows 7 my audio worked fine. When I tired the beta version of 64 bit I couldn't get it to work to save my life. Now I am running RC 64 bit and the audio doesn't work. I have a Sony RC210G. I have a aftermarket sound I think its a sigmatel. Any help would be great!
Audio problems!! I know you have heard it all before.
- Thread starter sleepys4
- Start date
Could you try running Everest please, and it should tell you the exact sound card you have. Without that it won't be easy to help, as we need to find the right drivers for it

I guess you've checked Windows Update already, and it can't find anything?

Do you have an onboard sound card and a separate PCI one (both activated)?
It looks like the Sigmatel one is the default one that comes with your machine, and the drivers are available for download here:

If you're using the C-Media sound card instead, get the 8738 one from here:
