tommy6x Posted August 31, 2011 Share Posted August 31, 2011 I think I have found something. This freezes are not coming from IRQs, it is OS X that switches when not needed from rear panel to front and viceversa. If I unplug and plug fast my headphones to the front panel after sleep (when rear works good), I can see iTunes' timeline pause, like in freezes. If I continue to plug and unplug, I can make iTunes pause for a very long time (until I break the front-panel port, I suppose ). I found that VooDooHDA works, I think jack recognition can be enabled, but without I didn't notice any freeze, it just works, front and rear. Now, since I've seen others with this motherboard with ALC892 using AppleHDA, I'm wondering why I've this problems. In System Preferences> Sound, 4 outputs are listed, 2 internal speakers, 2 digital output. Only the first internal speaker outputs to front and rear. Is this normal? Is there anyway to make OS X stop switching? Link to comment Share on other sites More sharing options...
