smorf Posted June 5, 2012 Share Posted June 5, 2012 hi all, i seem to have problems with USB audio. I tried different USB Ports on my rig, also i used 2 different usb-audio devices (C-Media and a terratec aureon) which work fine on my macbook. For example during videos (VLC) or when using Voip (X-Lite) i hear crackling noises at radom times and every now and then USB audio starts to fail completely (audio and mic). When I restart the applications, everything works, sometimes i also need to unplug the usb audio adapter and plug it back in. I have a Asus P5L-MX mainboard, and in 10.5/10.6 i used an alternative IOPCI family kext, which was supposed to fix "minor usb issues", according to the HCL. This kext does not seem to work in 10.7.4, i get instant kernel panics on boot. Can anyone point me a way to fix this? thanks in advance!! smorf Link to comment Share on other sites More sharing options...
