enodr Posted May 22, 2007 Share Posted May 22, 2007 Hi, This is a very strange problem... Sound stopped working (I think after installing Quicktime Mpeg2 support, but not sure if it's linked). I have a D865PERL Intel motherboard with onboard sound. It's an AC 97 Intel chipset. Sound was working perfectly, then tonight nothing (volume control is still available. Sound panel says I have an AC97 even if System Profiler says I have "No Built-in Audio."). After a long hour I tried to plug the speakers on the other output (the black one - don't know what they are for). And... it works... I think no stereo but it works. I think some kext is messing. Here is the output of kextstat: Index Refs Address Size Wired Name (Version) <Linked Against> 1 1 0x0 0x0 0x0 com.apple.kernel (8.8.1) 2 17 0x0 0x0 0x0 com.apple.kpi.bsd (8.8.1) 3 27 0x0 0x0 0x0
