I'm having trouble with my AUDIO DRIVERS in Windows 7 RC. I've tried almost every single version available, but nothing works for good. My thread refers to the problem people are having in this thread (http://h30434.www3.hp.com/psg/board/message?board.id=Sound&thread.id=609) (STacSV64.exe IDT PC Audio using 50% of cpu)
After installing the latest driver (SP42549) it seemed to resolve my problem, but it returned. The Laptop will get VERY slow, everything will not respond for a few minutes, and the CPU usuage indicates that its the AUDIO. Have someone managed to solve this yet? It's really frustrating... The AUDIO works FINE with the Default Win7 drivers, no problems at all, just when installing the IDT drivers I get this problem.
FWIW, for the time being you answered your own question with the statement: "The audio works fine with the Default Win7 drivers, no problems at all...." You are running a RC with IDT's notoriously buggy drivers - some things just won't be what you want and this is likely one of them. The bad news is that Windows Update offers an updated IDT driver for the RTM and while it didn't hit the processor the way you describe, it did negatively impact both boot times and overall performance. You can probably also tell by my use of the past tense that I deleted the IDT driver and went back to the stable, low resource, Microsoft option. Actually, there are currently two updated drivers for my HP laptop on Windows Update and both resulted in a major performance hit (and both are also now off my machine). The other was for Intel's display driver and its impact was even worse than the the IDT mess. I think on this one you really will just have to wait on HP for a better solution....
