Fast Track C400 pitch / sample rate problem

[nortle]

Hello,

I experience the following problem since I bought the unit 1 1/2 years ago and it's quite annoying. Finally I found the way to this forum (since Avid seems to try everything to avoid help or serious driver updates).

The problem:

Restart the Computer. The whole audio output is now pitched a few semitones higher. This happens irregular. Sometimes it happens, sometimes it won't. Tried to find a scheme, but there is no.

Go to C400 Control Panel -> Setup -> Samplerate
Switch to 48000 and back to 44100.

Problem solved.

This appears on Windows 7, 8 and now 10. Tried different driver versions (of course also the most actual).

Anyone out there who has the same problem? I think that's a No-Go for a "Pro" audio unit. Or may it be that my unit is kind of "broken"?

Thanks for any contribution to this issue.

Do you have the C400 set as the default playback device for Windows? If so, that could be part of the problem. Personally, I have my audio interface set to be used by my DAW only, and run an output from it to my sound card, speakers connected to the sound card. This prevents a lot of problems with Windows/iTunes/YouTube etc. taking over the audio interface while you're trying to record.

If you have a session set @ 48000 and Windows wants to play a sound, it will likely be @ 44100, and mess with the interface.

Thanks for the answer.

Yes, it is the standard device. That coiuld be part of the problem.

So I should connect my (onboard) sounds output with the input of the C400 to get all the non-daw sounds? Isn't there a loss in quality?

Here's my connection setup, if it helps:

Audio interface set in DAW, Creative sound card set as default Windows audio device.

SPDIF out of interface to SPDIF in of Creative (you could use analogue in/out)
Monitors connected to output of Creative

This way your interface is left alone to do DAW related tasks, but all audio is still passed through to your speakers.
