I tested changing to another power socket, and now it does power on again. But I cannot get output from ANY channels at all. The noise still remains, and I made a video out of it, which I will upload soon.

Now this is strange. I changed the Clock Mode around, and there was a high-pitched whine on all modes, except for 32000 Hz. If I use any other internal clocks than 32 kHz, there is no sound at all, only a hiss that seems to follow the sound that plays back, except in pure white noise. But in 32k, the unit works like it should. This is definitely some internal clocking error inside the unit controller! It's like the xtal or prescaler is somehow corrupt?

Of course, when I switch to an application that has a 44,1 kHz file open, the Fireface automatically changes back to 44,1 kHz Internal clock, and again there is only noise and no sound.

The last time I flashed it was back when v1.70 was released, and it worked just fine even after that. But it's strange, since these problems only started in Windows 7. In WinXP, I never had problems like this. But it could just be a coincidence. I've had the Fireface since summer 2007, so maybe it's somehow related to long-term use?

But this still does not explain how the unit just shut down on its own during playback... maybe some buffer got too full with corrupt data? Or some other overflow.

Edit:
There is a cricket (the insect) chirping sound in this 32 kHz setting, no joke! Constant and on time, like a metronome.

Hello,

please mail me the unit's serial number and a copy of the invoice, and I'll see what can be done. But only after January 6th...

Wrong thread, it seems...

So always remember to throw away any RME device before you start a recording session, if it's close to the end of the warranty period.

So how much is your estimate, based on the known facts so far, for the repair? If you don't wish to reply here, you can also e-mail me.

Ok. So what is the procedure? Do I send it to the local specialist listed at the website, or directly to Germany?

Well, the funny thing is that the local distributor told me to contact the retailer, and the retailer told me to contact you. So I can't get anyone to check/repair it.
