iTu Posted May 18, 2011 Share Posted May 18, 2011 Hello everyone, I have 10.6.2 on my 7520 almost everything work well exept of audio card and sleeping mode. I tried many kexts, internal/external soundspeakers work well, but line-in and mic's still don't work, so when I'm runing garageband it show's core audio error. I've done linux dump: codec1_dump.txt Link to comment https://www.insanelymac.com/forum/topic/257303-alc268acer-aspire7520g/ Share on other sites More sharing options...
