Intel hd4000 - sound over HDMI

M

mzperx

Hello All,

I have seen that "sound over HDMI" has been discussed a few times but still I am not able to resolve my situation. I have FreeBSD 9.2, Intel i7 with hd 4000 card.
Code: 
cat /dev/sndstat

FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <IDT 92HD93BXX (Analog 2.0+HP/2.0)> (play/rec)
pcm1: <IDT 92HD93BXX (Analog)> (play/rec)
pcm2: <Intel Panther Point (HDMI/DP 8ch)> (play) default
pcm3: <Intel Panther Point (HDMI/DP 8ch)> (play)
pcm4: <Intel Panther Point (HDMI/DP 8ch)> (play

I did:
Code: 
/boot/loader.conf

snd_pcm2_load="YES"
snd_hda_load="YES"

I have sound on my laptop I just can't get it through HDMI (xrandr says HDMI3).

Thanks for your help.

EDIT: so I guess I need to configure snd_hda in but don't know how. The relevant info:

Can you post your xorg.conf please. I have an HP Elitebook 8470p that comes with hd4000 and wiered things happend. I managed to start X but it's running very poorly (lag in moving windows around)...it's using vesa driver. Also when i quit X i have to reboot because it's not showing the command line anymore...just blank screen. Also what modules have you loaded for this videocard ? or compiled in the kernel if that's the case.
Thanks.
 
Unfortunately I can't because until this issue is not solved I switch back to Arch Linux (I use my laptop for multimedia too and I have to have HDMI audio connection).

But I can tell you what I did: compiled Xorg with WITH_NEW_XORG and WITH_KMS options then ran Xorg -configure. The screen went black but after restart I found xorg.conf.new and added "AccelMethod" "sna" to the Device section (which included the intel driver already). That was all.

However I think your problem lies somewhere else. How do you know it is using vesa driver? Because for me Xorg worked fine without compilation or any configuration.

Have you installed a composite manager?

I too could not exit X but I think I read somewhere that was perfectly normal so I did not worry about that (I can't remember the specifics).
 
This works out of the box for me when I do # sysctl hw.snd.default.unit=2. To check which unit number you should use, use # cat /dev/sndstat.

With this command # sysctk hw.snd.default_unit=4 I can hear something from the HDMI port but this is something unrecognizable raw noise. I changed the setting in loader.conf too (snd_pcm4_load="YES").

The laptop plays the music fine. Any idea what causes the distortion in HDMI? Thanks.

Ctrl-Alt-F1 should end your X-session and return you to a virtual terminal. Then CTRL+c to get to a prompt. No need to reboot just to get out of X.

He's using the KMS, currently there is no way to unload the module when X shuts down, so the only way to get back to a virtual terminal is to reboot. 10.0 is supposed to fix this.
