My setup is Foobar -> Waspi ->Ayre QB-9 etc. The QB-9 can't output in 16bits, it only outputs in 24 bits and I can change the frequency in Vista but I usually just leave it at 96.

Now here's my question; all my perfectly ripped FLAC files from vinyl and DVD audio are 24/96 but they sound terrible. They almost sound static-ey with some extra noise mixed in. Does this make any sense? Are they being double upsampled or something? In fact, 320kbps mp3s seem to sound better.

does the problem persist with the onboard sound output?

So you have 24-bit selected in the foobar output preferences, than maybe your buffer length is too long or too short? Which OS (just curious, not for debug purposes)?

In foobar output I have 24bit selected and in windows vista 32bit I have 24/96 selected.

I had a similar problem with optical out of my macbook pro. I hooked it up to a Boulder Digital Preamp with built in DAC. 24/96 sounded like you've described. Intermittent with lots of static, terrible. When I set the sample rate down to the next step down it got a lot better. I couldn't figure it out. I brought it home and hooked it up to my AVR (Yamaha RXV-730) and set it to 24/96 and the receiver seemed to decode it correctly. I'm not sure what the diagnosis is either. But I've had a similar issue.

It is a very interesting thing when using this type of equipment various upsampling can happen. Are you using WASAPI on vista?
