[Solved] Gentoo + HDMI+ HDA Intel = no sound

Message

MorningWood · Post by **MorningWood** » Sat Oct 29, 2011 8:49 am

Hey guys,
I have my Gentoo/XBMC setup working pretty well with the exception of one large kink; no audio through HDMI.
I'm running everything on a first generation aTV and according to most of the how-to guides audio through HDMI isn't possible but I've done some research and noticed some people got it working with Alsa-Drivers but I am using the gentoo- sources 3.1.0 kernel with alsa modules already compiled in so I was wondering if anyone had any other way to get sound through HDMI.
I have read the guides and the xbmc/gentoo/atv forums but either I'm too dense or this is a very isolated scenario.

Any help would be greatly appreciated. Here are my outputs:

Try this. Grab a cd track, let it be wav format and have a sample rate of 44100 or 48000. hdmi tvs may not play all sample rates (mine doesn't). The bitrate is something else doesn't matter here.

played the test track by running

No error message, no sound: are your volumes up?

Code: Select all

alsamixer -c 0

(0 id the default anyway) Enable the outputs with m key, raise them up. aplay error messages would indicate a bigger problem, so you're doing not so bad.

I raised the volume on the TV as loud as it could go thinking maybe it's just a low volume bug (was really hoping it wouldn't randomly start working and kill the tv speakers :p) and here's a screenshot of my alsamixer:

Shouldn't HDMI be associated with Nvidia?

whig · Post by **whig** » Sun Oct 30, 2011 8:26 am

You are loading the nvidia binary driver, I didn't see that before |:)

The aplay -l ought to list the nvidia output. But your card is a 7300? That can't do vdpau for one thing, and I don't know about hdmi audio to be sure.

Also required is nvidia-hdmi _alsa_ support. I'll think about this take a look at this in the meantime.

Yeah, I was afraid of that. I've read several posts noting that nvidia drivers have since disabled audio over HDMI (at least for this card) but most of them are from 2009, so I'm hoping there might have been a change since then. The device in question is a first generation Apple TV and I posted on the atv-bootloader google groups and the gentleman that helped me setup the kernel also noted that he has audio over HDMI working but he's using the nouveau drivers. Could this have some bearing on the situation?

Also, I'm sorry you lost me with the nvidia-hdmi _alsa_ support.

DawgG · Post by **DawgG** » Sun Oct 30, 2011 2:58 pm

i just got this to work with the guide from nvidia (link in whig's post) - just make sure you strictly follow everything in there. My setup is a little different from yours but similar:

VGA compatible controller: nVidia Corporation GT218 [NVS 3100M] (rev a2)
nvidia binary driver
pulseaudio (configured as in the nvidia-howto)

make sure the nvidia binary driver is loaded; the tv is plugged in before x starts and you use the correct devicenames for alsa/pulse (mine are a little different from the ones in the howto). using /etc/asound.conf messed up alsa so i decided to use pulseaudio and it works; to play a movie on tv with hdmi sound i configure pulseaudio with pavucontrol and use mplayer -ao pulse <file>

Also, I'm sorry you lost me with the nvidia-hdmi _alsa_ support.

this is in the kernel-settings for alsa: go to device-drivers -> sound -> alsa -> PCI devices -> Intel HD Audio and there you activate everything you need (or maybe just everything to make sure). i think there it's best to use modules where possible.

even though Free Software is much better than binary bull the nouvau driver is not likely to support hdmi output with sound yet: http://nouveau.freedesktop.org/wiki/FeatureMatrix

GOOD LUCK!

DawgG,
Thank you for the feedback!
In regards to hdmi audio, the Intel HD Audio module is decked out with all the options enabled. I keep getting lost in the constant reference to Nvidia/Intel.
I am slowly reading over the guide as it's pretty lengthy and I do not want to make any mistakes. Hopefully my next post will be that of happiness.

whig · Post by **whig** » Sun Oct 30, 2011 6:54 pm

Good luck. The _alsa_ support I was referring to is indeed provided by CONFIG_SND_HDA_CODEC_HDMI in the kernel. I was stung by it some time ago - my new GF210 had the nvidia binary which did the display okay, but vanilla kernel.org didn't have that hda support for the GF210 until later. I patched.

MorningWood · Post by **MorningWood** » Sat Nov 05, 2011 5:14 am

so apparently Audio over HDMI in regards to this application is just not possible. At one time it was, but that was a rather dated Nvidia driver on an old kernel. What I'm trying to do right now is get video out via HDMI (which has been accomplished) while getting audio out with rca (not so much).

I'm following this page:
http://code.google.com/p/atv-bootloader ... udioDriver

but between the fact that I'm in over my head, the page is for Ubuntu, and is pretty dated....progress has been slow.

Any words of wisdom?

Also, according to this and a few other pages, apparently adding said option to either /etc/modprobe.d/options /etc/modprobe.d/alsa.conf or /etc/modprobe.d/alsa-base will get RCA audio out working without the need for a patch but none of these files are present and creating them does nothing. :/

RCA - is that normal intel hda motherboard audio? Your above commands listed it and showed it playing that way without error (no speaker plugged in?) Does your system already do

Code: Select all

dmesg | grep hda_codec
hda_codec: Detected AppleTV RealTek Subsystem ID

I know this reply is long overdue but I had given up on this project for a while and basically just had the apple tv laying around my bedroom. I've missed having a dedicated media device so I'm right on the brink of just wiping and restoring the default setup. However, I've gotten this far and have invested way more time than I want to admit to so I'd love to at least get sound out via RCA so thank you for your help guys and any additional help would be greatly appreciated.

To respond to the above comment, yes, my system already does.

whig · Post by **whig** » Tue Jan 24, 2012 8:27 am

Your aplay -l shows the devices which is a start. But the listing on my pc shows the kernel module too. This could be your alsa-utils are old or that your cards lack kernel support. lspci -k to check.

Once the device and sub-device numbers are known, and are not 0, create an /etc/asound.conf

Code: Select all

pcm.!default {
  type hw
  card 0
  device 1
}

MorningWood · Post by **MorningWood** » Tue Jan 24, 2012 5:27 pm

whig, thank you once again for your ongoing support. Here is the output of the lspci -k command:
http://i.imgur.com/dFqsa.png

So at this point would I create an /etc/asound.conf configuration consisting of the following:

Code: Select all

pcm.!default { 
  type hw 
  card 0 
  device 1b
}

?

Pardon me if this is a silly question; I'm a bit rusty from my hiatus.

MorningWood · Post by **MorningWood** » Tue Jan 24, 2012 6:13 pm

YES!!!! I got audio through my tv with rca. So audio IS working. Thank you so much whig!
Now if I could figure out how to configure it to work in xbmc.

E: Works perfectly through my receiver as well.
Ran aplay -D plughw:0,0 test.wav in x11.

If anyone knows anything in regards to xbmc audio settings your expertise would be appreciated here. I think what I would need to configure would be the audio output device and set a custom device but I don't know what to put.

whig · Post by **whig** » Tue Jan 24, 2012 6:31 pm

Congrats! The alsa numbers don't need to be specified if they are the default 0. Sometimes udev will load them in random mucking up the order. That's before the alsa service starts too.

You can mark this thread as [solved]

Thanks whig. Would you have any idea as to how to go about getting audio working in xbmc?

Going to try hw:0,1

E: Apparently today was a good day for aTV tweaking.
Tried. hw:0,1 didn't work.
tried hw:0 and currently enjoying some music. So glad I didn't give up. Once again THANK YOU WHIG.

whig · Post by **whig** » Wed Jan 25, 2012 12:11 am

Cheers. I don't know anything about xbmc though. That might be better answered in a new post with that key word in the title. I thought about sox but that would just pipe recorders to a playback device, not playback to another playback(?) Alsa can duplicate out streams to another device. It isn't used much because the clocks are different and the streams get out of sync. It might work in your case who knows. I haven't tried it. Search the alsa home page if you want to go down that path.
