Hi Dark Mantis,
Thanks for your interest in the problem.
I am running 32 bit at the moment, but I have also tried 64 bit and the same problem persisted.
It is a strange problem but this is basically the description...
I have a WIN7 media center PC, which I use for TV, music, video... The PC uses an external USB DAC for the audio, which connects to the HIFI. Everything is controlled through WMC.
The problem is that the audio crackles when I play video files if WMC/WMP and the DAC are used together. The DAC uses the generic win7 USB DAC driver.
This problem did not happen with VISTA or XP, and I have tried updatding everything: drivers, BIOS,etc...
My thoughts are that either WMC audio buffer scheme is doing something very silly filling the buffer with crakling noise, ir the generic win7 USB DAC driver is not working well
Thanks again
