P7P55D-E Pro odd audio problem (via chipset)

I have a mostly working Mountain Lion install on my asus P7P55D-E Pro, but the audio is the only major outstanding issue.

The analog audio works - but only if the mouse is moving. If the mouse is not moving, the sound is very slow motion and distorted. If i keep moving the mouse around, the sound is perfect. I think the root cause is the CPU being idle and/or reducing its frequency when nothing is happening. Similar audio issues I've seen "solved" by hacking the CPU to always run 100%.

Is this a common problem and/or does anyone have any advice?

I'm currently running the voodoo seb235 kext, all others have given me a kernel panic. I've also referenced the following forum posts without luck:

thanks!

Solved the same problem, ehm, more "traded a problem for a problem", by using EasyBeast (specifically NullCPUPowerManagement.kext) and now the audio is working (tho on some occasions it still cracks a little but more due to regular amplifier problems) BUT sleep isn't! I guess the new kext does't allow him to do that... but still, better have good audio than sleep

That worked! Thanks!

I'll do some research, but what are the side effects of this kext? CPU will run hotter at idle? turbo boost gone?

I have a pretty powerful CPU so I have no need for OC/Turboboost but as I said, the biggest thing is that sleep is gone. With the kext I assume the CPU is always running at full frequency so that is perhaps something I would like to avoid if I can. And again I said that audio was still not that good, I still hear crackles from time to time :/


edit: forgot to mention that no, using the kext does not heat up your cpu so it doesn't hurt your pc

I just ran into the problem when I upgraded from 10.8.2 to 10.8.3 on my ASUS P7P55D-E PRO. System beeps worked fine, and other audio (iTunes music, YouTube videos) would start to play but within a few seconds the audio would become staticky and choppy.

I solved the problem by installing VoodooHDA 0.2.2 (the latest version in MultiBeast that didn't say "this driver may be unstable") and rebooting. No other configuration necessary; the audio works fine now.

(After installing it and before rebooting, the audio was still choppy, so a reboot is necessary to get the system to pick up the kext.)
