Jinx Posted August 22, 2005 Share Posted August 22, 2005 Ok, so i was playing around and found this Applications -> Utilities -> Audio MIDI Setup Go to Properties For -> AC97 Audio (PCM) There should be two, one is input, the other is output the output is what we want Now... Theoretically the problem with higher pitch is due to a Hz imbalance.. and right there on the right, we have the frequency It seems to be too low... Change it to 48000hz That fixed it for me Hope it works Good luck Link to comment https://www.insanelymac.com/forum/topic/854-howto-fix-the-ac97-audio-chipmunk-problem/ Share on other sites More sharing options...

joedirt Posted August 25, 2005 Share Posted August 25, 2005 I still have stuttering (sounds like PCI problem) and my AC97 is the same vendor ID as original kext (ie. I didn't edit anything) Dell 5150 (Sigma Tel audio) Link to comment https://www.insanelymac.com/forum/topic/854-howto-fix-the-ac97-audio-chipmunk-problem/#findComment-6889 Share on other sites More sharing options...
u157206 Posted January 20, 2006 Share Posted January 20, 2006 Just in case anyone can help me on this, I only have an input on the audio midi setup, there is no output (Although I am able to play music almost flawlessly, I just checked a movie and it was all crackly). I was also wondering if anyone knew how to properly install a midi driver so that you could play a keyboard in garageband. Please I am new to this so if I am doing something wrong please correct me.

williwilliwilli Posted January 31, 2007 Share Posted January 31, 2007 Hey, I have been patiently searching before asking this now. I still have chipmunks in my hack. Audio input and output work (onboard ac97) but the output is still high pitched. In my case, changing the sampling frequency does not make a difference!! Any Ideas? Anyone still having that problem? Thanks.

deniser Posted August 4, 2007 Share Posted August 4, 2007 Just gone to try this. It is showing up as AC97pcm as my default device but only as input there is nothing there for output. Everything is plugged in correctly. I have bought a usb sound card waiting for it to arrive.
