Hey,
I'm experiencing sound issues with both DX9 and DX11 client since I istalled the expansion.
I'm using a G35 headset from Logitech that has been working without any issues with any 2.X patch. Since 3.0, sound levels are not consistent (volume is changing in rapid succession), music sometimes stops playing completely as well as the infamous DSP lag crackling (that might be related to load...).
Any suggestions? Anyone else?
