Aaronious Posted May 2, 2011 Share Posted May 2, 2011 Relevant System Info: Gigabyte P31-ES3G (ALC888) (s/pdif (2 wire) motherboard header connected to) nVidia GeForce 9500GT (connected with HDMI cable to my HDTV, then optical cable to my Home Theater (for decoding DTS/AC3 5.1) Dear Omnipotent Ones, I used the ALC8XX, AppleHDA Rollback, and ALC888 Enabler from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to get sound through my HDMI cable. It works great for stereo sound, but when I'm using any 5.1 Passthrough (in Plex, Boxee, etc) I get frequent audio "drop outs" and occasional distortion after several minutes of viewing. If I stop the video and then resume it, the audio signal is clear again for several minutes, then drops again, distorts again and so on. **I have ruled out programs, cables, HDTVs ability to passthrough DTS/AC3, and Home Theater as the problem. So I'm guessing it's the kexts and hardware. Any advise?... hardware upgrades?... DSDT alternative... or black magic you can recommend that might provide a constant audio stream? Please point me in the right direction! Thank you.

Aaronious Posted May 5, 2011 Author Share Posted May 5, 2011 Does anyone have a system that you've tested and has a perfect DTS/AC3 passthrough? I'm open to upgrading my motherboard or graphics card if it will help. If so, please share your specs. Thanks!
