Thread: Z77 & i3570 on board graphics HDMI issues (audio and video)

htpc using asrock z77 pro i5 3570. have razer ac1 sound card using toslink avr , intel 9400gt installed. hdmi output routed through pioneer vsx23 panasonic plasma.

problem 1: hdmi video out via on-board graphics results in snow , period "glitch". bios screen shows fine kdm , gdm both result in snow on plasma. installed 9400gt , works fine. on-board graphics not acquiring pioneer edid or there other other glitch should looking at.

problem 2: board has "hd intel graphics" including hdmi out port presumed allow hdmi audio out. however, no hdmi audio device shows in pulseaudio options or lspci. ubuntu (precise) or linux not have driver recognizes hdmi device in on-board graphics or missing else? i'm not above saying fit , getting new video card 'just works' i'd hoped on-board graphics of 3570/z77 golden instead of non-functional. here lspci results:

hi, have similar problem. mainboard gigabyte ga-h77-ds3h, has intel h77 chipset (a budget version of z77).
looked forward connecting pc tv single digital cable instead of previous vga+sound, disappointed when saw hdmi carrying video only.

searching board, found issue solvable in windows by updating drivers intel's latest.
common trap people confuse audio , video chipset in problem: though want audio, video chipset support important, because passes sound hdmi socket.

so, hm, no solution yet confirm issue. tried start jockey, no proprietary driver available on-board graphics card.

maybe later kernel update things start work. if pavucontrol 1 day shows "intel display audio" had not seen before, have struck gold.

intel not seem offer binary blobs linux might try out (though prefer stick vga, not bad).
