So, I found out that iTunes has Wasapi built in by switching from Direct Sound to Windows Audio Session. It worked fine for a while until I installed my new video cards (Upgraded from 580 SLI to 780 SLI). Now every time I use Windows Audio Session in iTunes it causes static, crackling, and distortion every 10 seconds or so. It's pretty random.
Now this problem is fixed if I switch back to Directsound, but I'm curious as to why iTunes can't use WASAPI. I use the WASAPI plugin in Winamp and that works fine, but a lot of the songs I've bought through iTunes are AAC Protected, so I can't listen to them in Winamp.
Currently running Windows 7 64bit with Titanium HD and iTunes 11.3. Bitrate is set to 44.1 kHz and Bits per Sample is set to 24.
I wonder if this is related to the Titanium HD card itself, because another problem I've been suffering through since I bought the card two years ago has been that after listening to audio for a while on say iTunes, then switching to a Youtube video or Winamp can cause the sound to create a large amount of static and distortion that will stay until I either switch modes in Creative Control Panel or completely restart my computer.
Any help on both these problems would be appreciated.
