audio skipping [ clipIfNecessary() ]
« on: May 25, 2009, 12:14:35 PM »
The audio is not smooth when there is a higher cpu workload/hdd activity (i.e. skipping)
This is really annoying when listening to music. :-\

The computer is the aspire one with alc268 & intel atom, and using the VoodooPower.kext

I had the same problem. Try the version without prefpane. Works like a charme for me.

I am actually using the version w/o the prefpane, svn r8 to be exact.
I think this may be caused by the voodoopower.kext because i had kp/distorted audio with the old driver when running on battery only.

I'm using the VoodooPowerMini. Don't know if this makes a difference.

Hi.

I have the same problem with my ASUS N10Jc audio.

I get a lot of the clipIfNecessary messages and audio skips badly.

I notice one thing though, if I keep moving the mouse (either on the trackpad using voodooPS2 or an usb mouse), the audio becomes a lot smooth and almost skipless, even though I still get clipIfNescessary.

As pointed out at http://code.google.com/p/voodoohda/issues/detail?id=30#c5 setting a lower audio format sampling rate gives less audio skipping.

Also if I remove the AppleIntelCPUPowerManagement kext, audio skipping completely goes away.
