I used Windows 7 professional 64-bit, and connect to my DACmagic with a USB cable.
Everything was fine till just now when it decided it would delete the default driver "C-Media USB Speakers" or something along those lines....it's not on the list anyhow.
I've tried restarting.
It's not recognising the DACmagic when I plug it in...
I've googled it but only get info about drivers changing, not disappearing.
Also when I turn it on, there is a high pitched squeal it makes, which goes quiet then, but it's annoying, even if I only notice it when there's no sound, spesh cos I have (I think) tinnitus.

I am basically at a loss here but don't look forward to waiting ages for a replacement.
I'm not sure if I'd just be better off replacing the optical cable that went missing at the last meet.

I'd just get a cheap optical cable to skip drivers completely. It's the reason I don't use USB with my compass.

Windows 7 must have a system restore? Did you try that with a previously known good configuration date?
I'm pretty sure it would restore the driver...worth a try anyway...

Thanks Ro-amp.
I'll try that...then if it doesn't work I'll try the DAC on my mums PC...and then I'll get an optical cable (again).

Either way, you have to reinstall the onboard sound drivers. Just try that, and see if it works. It might just be that you uninstalled the 'HD Audio' drivers, which is a basic thing, and Windows really doesn't like that.

If I recall, the DACMAGIC doesn't even have drivers. So using an optical cable would be just as difficult.

It needs them for Windows 7. See DacMagic FAQ

Well the optical option is still showing up under playback devices even though it's not being used...so I think I'll just buy an optical cable. Thanks.

Just re-download the new Windows 7 driver:

C-Media CM108 Like USB Audio Driver 6.12.8.2104 for Vista Driver for Windows Vista / Windows Vista64 Free Download - Softpedia

Select the second "Select Download" option for Windows 7 PCs. It should to the trick.
