Rob Red Beard Posted May 1, 2007 Share Posted May 1, 2007 Keywords: AC97 VIA Vinyl 8237 Via Audio P4M800Pro Ok - so I've read a lot of posts here with people saying that they have audio on their board but only the left channel. You might also notice that it is somewhat distorted. I am bit new to the mac, but I'm not new to unix, windows, or PC hardware (15-20 years experience using, building, and programing all of the above). My board is an HA P4M800Pro ML. It's a VIA chipset and the best I can get on the audio is that it's a via vinyl maybe the 8237 - but that isn't clear. Running JAS 10.4.8 on a Celeron D (sse3) 2.6ghz - 1.5gb ram. Extensions loaded. In the system profile-> Extensions, I've got both AppleAC97Audio and AppleAC97AudioVIA loaded (did this automatically). But when I look at the ...AudioVIA extension, it says : "Dependency Errors: com.apple.driver.AppleAC97Audio: No valid version of this dependency can be found" Please note again - version 1.0.0 of AppleAC97Audio is running, and with no known errors. Hardware->Audio (Built In) shows no built-in audio BUT audio DOES play, out of the left channel. That's the best I can do here.. Has anyone fixed this issue with VIA onboard audio?

Has anyone fixed this issue with VIA onboard audio? Thank you for your replies, 2 things. 1. The Audio out must be set as 48000, it defaults to 44100 causing distorted audio. Goto Applications -> Utilities -> Audio MIDI Setup and change the Audio output frequency to 48000 2. You need a patched driver for getting stereo output. The driver is available here! and follow the instructions in that thread Cheers Link to comment https://www.insanelymac.com/forum/topic/49888-via-audio-left-channel-only-issue/#findComment-358773 Share on other sites More sharing options...
