Onboard AC'97 - Distorted UI Sounds

Hey Everyone

 

I am using Leopard 10.5.2 on my PC and thankfully sound and lan both worked OOB.

 

BUT when any UI sounds play like 'Sosumi' it sounds all distorted and unrecognisable. However when i play music from an MP3 or play the same UI sound files (System/Library/Sounds) in iTunes it plays perfectly so im guessing a OS X problem rather than drivers.

 

A fix isn't mission critical, just wondering if anyone else has had this problem?

 

Thanks,

TheShadow

iTunes and system sounds have seperate volume controls.

 

Check all the sound control panels, especially audio/MIDI settings in the utilities folder.

Make sure none of them are set to 100%.

 

I don't see how it can be a FSB speed problem if it only affects system sounds but there you go.

I had this exact problem, it turned out that it was because I was using a SSE2 processor. Bought a new processor with SSE3 support and the problem went away! I guess the SSE3 emulation has a few bugs in Leopard.

 

You could also try changing the sample rate in Audio MIDI Setup to 44100.0 Hz.
