x86_64 hdmi audio

**forum1793** · 06-25-2009, 09:07 PM

Radeonhd has allowed sound over hdmi for a while now (thanks to Christian).

But recently when trying x86_64 (64 bit) I noticed it didn't work.

I did recently get fglrx to output over hdmi on the 64 bit so I'm curious if radeonhd can do that also.

Using radeonhd here is the last messages from dmesg:

Code:

[drm] Loading RS780 PFP Microcode

hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj.

Note I get the same hda-intel message using flgrx with sound over hdmi working.

I would be nice to understand what causes this problem. I don't think it's something between x86 and x86_64. Are you sure you are using the same kernel, alsa and radeonhd in your new x86_64, when comparing to x86?

Maybe some app is in lower version, or maybe newer with regression? Is this the same version of radeonhd?

In other case Xorg.0.log and xorg.conf will be more interesting than dmesg output. Provide this as a good start, later maybe you'll be asked to provide registers dumps.

Exact same 64 bit environment between fglrx and radeonhd. Kernel used is 2.6.27.25 as I couldn't install catalyst with 2.6.29 or 2.6.30. Other than the kernel, the rest is from slackware64-current which has qt4 and kde4 but also kde3 libs from extra (subdirectory on disk).

Between 64 bit and 32 bit: using slackware-current (32 bit), using slightly different kernel (2.6.27.15 which I'm also using with slackware-12.2). Both fglrx and radeonhd output audio over hdmi.

Hardware, if I didn't say previously is the gigabyte with integrated hd3200 (780g). I think its GA-MA78GM-S2H (I'm not sure what rev as it looks like they have 1.0, 1.1, and now 2.0).

64 bit radeonhd xorg.conf

Code:

#	Option "HDMI" "all"            #xorg.log says not used

It's needed, and I don't know why Xorg.0.log could tell you it is not used... Maybe you were using radeon or very old radeonhd for a moment?

Please, add this to your config and test. You may also want to specify that "all" value to something like:

Code:

Option       "HDMI" "DVI-D_1"

. Values may be single outputs names from randr.

But what you missed was that code was from the radeonhd 32 bit xorg.conf which is outputting sound nicely over hdmi.

When Christian first added the changes to allow sound over hdmi, this option was needed. I think once he added it to master, it was used per default and so was not explicitly needed in the xorg.conf.

I think I added it back and then commented out as I was trying different things with the more recent gits for drm, mesa, and radeonhd.

The "all" function has worked for the 32 bit environment in past and I don't know why dvi would be used for integrated hdmi. But it won't hurt me to try. I will also try with commenting out the option to more closely match the successful 32 bit version.

Thanks

**forum1793** · 06-26-2009, 06:56 PM

Not sure if git branches I choose might be factor. For recent gits I am using the following branches.

drm -> agd5f's 3d
mesa -> r6xx-rewrite
radeonhd -> master
ati -> master

If these are not optimum for hd3200 please let me know.

**forum1793** · 06-26-2009, 08:58 PM

Huh, with fresh compile of gits, it started working. Not sure why.

Would pointing radeonhd git at r6xx-r7xx-support as opposed to master cause this?

For me and with gits as specified above (radeonhd->master), all that seems to be needed for audio over hdmi on 64 bit is:

Code:

Section "Device"
	Identifier  "RadeonVid"
	Driver "radeonhd"
	Option "HDMI" "all"
EndSection

Tried it without the Option "HDMI" "all" and no sound.

Edit: Yes, xrandr does show "DVI-D_1". Using Option "HDMI" "DVI-D_1" also works. Now I'll have to go back and try this on the 32 bit.

**bridgman** · 06-26-2009, 09:12 PM

radeonhd 6xx-7xx-support is probably missing a bunch of recent work

EDIT - yep, it branched off 6 months ago and last commit was 4 months ago so if you were pointing there you would be missing a lot

**forum1793** · 06-26-2009, 10:20 PM

OK, recompiled all gits as above in the 32 bit and sound works over hdmi and requires option hdmi all, or dvi... as stated above. So both 64 bit and 32 bit now seem consistent.

Was looking at xorg.0.log and saw dri was working so I tried glxinfo and it worked. Then tried glxgears and hard lock. Only power button worked (and of course power switch) worked.

I'll try these (hdmi audio) with 2.6.29 and 2.6.30 kernels next.

**forum1793** · 06-26-2009, 10:51 PM

Loaded 2.6.29.5 (slackware-current generic) with everything the same as above. Sound over hdmi works.

But, dri fails and windows move very slowly. Xorg.0.log shows:
