The problems of the previous drivers' are still there, I think it's just wrong that some of these are not fixed yet after a whole year...
The problems are:
Really annoying channel switchings (totally random)
Dolby Home Theater buggs on youtube and various other stereo applications (Windows 8.1) [Dolby Home Theater Speaker surround option does not work anymore since 8.1]
FlexBass glitches sometimes, it randomly inverts its settings, like suddenly the bass is gone, and if you deactivate Flex, the bass will return.
Sample Rate 192khz still pops and is bugging in games.
DTS does not work very well, if you use "Center Expansion", that feature will be like 100% on left channel and 50% on the right.
Do any of you guys have these issues?
