I think I experience similar issues. In my case the multi-channel pcm playback through HDMI doesn't work. Stereo and passthrough seem to work fine though !? It's hookedup to my TV via a yamaha receiver. I'm currently running Linux 3.1 with a G45 chipset. libdrm 2.4.27-1 xf86-video-intel 2.16.0-1 The eld seems be incorrectly parsed, though the kernel log didn't give much info. The eld info from alsa is rather empty: cat /proc/asound/Intel/eld#3.0 monitor_present 1 eld_valid 0 Using the same Monitor Asset Manager I was able to verify that the edid from (/sys/devices/pci0000\:00/0000\:00\:02.0/drm/card0/card0-HDMI-A-1/edid ) does seem to contain the correct information. I've attached both the edid and the output of Monitor Asset Manager.In addition I also run the intel_audio_dump. Let me know if you need anymore information. Cheers, Sander PS. Hope the attachments are not too big.
