Hi,
My problem is HDMI digital audio keeps disconnecting, Yamaha RX-467V AV/R is showing intermittent HDMI audio signal.
I'm using DSDT for my Gigabyte H97M-DH3 motherboard, and HDMI connected to Gainward GTX 680 nvidia card. I have no special kext used for audio/video (nvida card worked OOB, sleep/wake is OK, etc.). I'm using Clover boot in EFI partition.
Once I reboot my rig HDMI audio works flawlessly, but after two or three sleep/wake cycles, HDMI audio starts disconnection pattern, specially if I'm using Chrome (¿?). I've read about Chrome and HiDPI issues, but I don't think that could break HDMI sound...
Everything else is working OK, as far I know. Nvidia card is powering 4k DP monitor through DP port, with HiDPI scheme (4k displays are stunning), iMessage is working fine too, and so on.
Which is my best strategy?
1. Trying another DSDT. I'm worried about this because I'm not very good with DSDT compilation...
2. Trying several AppleHDA patched kexts. I thought this approach is for people with no HDMI sound at all, and that's not my case, so I didn't take this way before. But know I'm considering it.
3. I have spare 7970 card, but ATI personalities, injection, etc seems a very hard way to do things..
Any thoughts?
Thank you very much.
