So, this is a problem that I have been having for a couple years, but it's been getting worse lately.

Maybe 25-30% of the time when I play videos online (YouTube, Vimeo, other embedded streaming video formats on news websites, etc), my HDSP AIO pcie card crashes. The video freezes (and cannot be un-paused or re-played) and the sample rate in the HDSP settings panel gets set to 32000 hz and I can't change it back to 44000 (where I normally keep it). All audio freezes on my system and I can't play back any WAV's, MP3s, etc, once this happens.

The only fix is a full restart of my PC. My HDSP is the only soundcard that I use for my system - the motherboard's onboard audio is manually disabled.

Any ideas?
