I am trying to get sound working on kernel 2.6.39 (under archlinux x86_64 bit distribution) over HDMI to my digital receiver but without luck. Before this post i asked in #alsa for help, and everything we tried over there didnt get the sound over HDMI. I connected headphones to the green jack and ran speaker-test and there is sound over jack, analog sound plays fine. But runing alsamixer un-muting spdif/iec958/spdif (1) and trying to re run speaker-test doesn't output sound over HDMI to my digital receiver.

Note that on your device HDMI goes through Nvidia HDMI codec, thus it's irrelevant with ALC262 at all.  The machine shows an SPDIF output connected to ALC262, but this must be different from the HDMI output.  So, the first SPDIF/IEC958 setup is also irrelevant. The second IEC958 setup is for HDMI.

Thanks for explaining it, and you are right HDMI indeed goes through Nvidia HDMI codec, just in my case i dont get any audio signal through it. As you mentioned that above, I took coaxial and digital cable and connected it directly to SPDIF digital/optical, and did speaker-test and there was sound on my speakers. Tested with : speaker-test -c 2 -D hw:0,1 The above is also for both spdif outputs. So indeed ALC262 seems works just fine.

Crow, you might find the following document helpful:

I tried to use /etc/asound.conf for global settings (tooked from 2.6.35 archlinux i686 installation) but does not work with 2.6.39 installation, even I am not able to play analog sound: speaker-test -c2 -twav -l1 This above works without asound.conf, and it plays analog sound on headphones.

This is how i tried to play sound over HDMI: speaker-test -c2 -D plughw:0,3 -twav -l1

The above command does output sound on 2.6.35 (but just over Fron Right)

So, something was wrong even on 2.6.35?

With 2.6.35 this my Setup works somehow using HDMI (which is actualy what I want), with optical/digital spdif i didnt tested it recently, as with VDR/XBMC on first time setup I was getting some cracks on speakers, it could be also my digital receiver problem through (Onkyo TX-SR606), but using HDMI it doesnt cracks.

Crow, please try a more default command:

speaker-test -c 2 -D hw:0,3

I tried above command but without luck, nothing is comming to digital receiver. I dont even see ony display that it send any audio signal.

I run alsa-info.sh script on both installation and it can be found on (2) kernel 2.6.39 and (3) kernel 2.6.35.

I was hoping to get sound working with 2.6.39 (current official archlinux kernel) over HDMI by just un-muting spdif with alsamixer, but it seems not to be that easy.

It's Nvidia, so make sure that the video-driver side supports HDMI audio properly.  You can check /proc/asound/card0/eld#* file to see whether the monitor is properly detected and what ELD values are read.

ELD data isn't supported on the MCP7x chipset, so the ELD files won't appear.

As Warren wrote there isnt ELD files there.

Crow, which NVIDIA video driver are you using? Can you please try upgrading to the latest release from:

ftp://download.nvidia.com/XFree86/Linux-x86/275.09.07/

I am using that driver already, official archlinux driver: pacman -Qi nvidia Name : nvidia Version : 275.09.07-1 URL : http://www.nvidia.com/ Licenses : custom Groups : None Provides : None Depends On : kernel26>=2.6.39 kernel26<2.6.40 nvidia-utils=275.09.07 Optional Deps : None Required By : None Conflicts With : nvidia-96xx nvidia-173xx Replaces : None Installed Size : 4388.00 K Packager : Ionut Biru ibiru@archlinux.org Architecture : x86_64 Build Date : Tue 14 Jun 2011 07:08:31 PM CEST Install Date : Sat 25 Jun 2011 08:57:15 PM CEST Install Reason : Explicitly installed Install Script : Yes Description : NVIDIA drivers for kernel26.

I dont have any GUI here, trough i installed xorg,nvidia,alsa and prepared for VDR/XBMC. Greping lsmod i see nvidia and snd_hda_codec_hdmi modul loaded.

With 2.6.35 kernel it is snd_hda_codec_nvhdmi modul trough (alsa-info.sh output I linked in first post)

SOLVED: Well I must mark this as solved. Inside .xine/config i have :hdmi as output device defined, and i get sound on my speakers using just HDMI as connection to my digital receiver. grep "^[^#]" /var/lib/vdr/.xine/config .version:2 gui.deinterlace_by_default:1 gui.osd_enabled:0 gui.dropped_frames_warning:0 audio.driver:alsa audio.device.alsa_default_device:plug:hdmi audio.device.alsa_front_device:plug:hdmi audio.device.alsa_mixer_name:Master audio.device.alsa_mmap_enable:1 audio.device.alsa_passthrough_device:plug:hdmi audio.device.alsa_surround40_device:plug:hdmi audio.device.alsa_surround51_device:plug:hdmi audio.device.alsa_surround41_device:plug:hdmi audio.output.speaker_arrangement:Pass Through video.driver:vdpau video.output.vdpau_enable_inverse_telecine:0 video.output.vdpau_hd_deinterlace_method:bob video.output.vdpau_sd_deinterlace_method:bob video.output.vdpau_deinterlace_method:bob video.output.vdpau_display_queue_length:4 video.output.vdpau_sd_only_properties:noise+sharpness video.processing.ffmpeg_choose_speed_over_accuracy:1 video.processing.ffmpeg_pp_quality:0 video.processing.ffmpeg_thread_count:2 engine.buffers.audio_num_buffers:275 engine.buffers.video_num_buffers:1800 engine.buffers.video_num_frames:22 engine.performance.memcpy_method:sse

I actualy didnt test it before with xine, and was trying just speaker-test which seems could not output sound over :hdmi (0,3). Maybe there is bug in speaker-test, but then after getting it work with xine i could test it with speaker-test to.. Then i reboted my htpc and got it.. It seems HDMI output isnt activated, or speaker-test cant activate it somehow.. $ speaker-test -c 2 -r 48000 -D hw:0,3 $ speaker-test -c 2 -D hw:0,3 Both above command dont work after first boot. And with aplay i get this (command from 13.7. Test Playback With ALSA Physical Devices (1): aplay -D hw:0,3 /usr/share/sounds/alsa/Front_Center.wav Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono aplay: set_params:1065: Channels count non available

But if i run xine, which connects to VDR i get sound, and after killing xine, and re-run speaker-test i got audio over HDMI just fine... $ speaker-test -c 2 -r 48000 -D hw:0,3 $ speaker-test -c 2 -D hw:0,3

Even aplay play the file with 'hwplug' I dont get anything on speakers (trough xine, and after killing xine, speaker-test play sound just fine): $ aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono $

I don't quite understand that last sentence. Just to be clear, audio over HDMI isn't expected to work unless the NVIDIA binary X driver is installed, X is running, and X is being displayed over HDMI.

Well when I was using speaker-test command I was in command line interface. Nvidia binary X driver is installed and loaded, X isnt runing, nor is xine. They are started after, with vdrclient startup script. Trying speaker-test befor X and xine, does not give me any output to speakres (even, speaker-test plays, no error output just nothing on speakers). Now i start vdrclient script which do (1) and (2) and i get sound on speakers. Then i stop vdrclient, and i checked X isnt runing anymore nor is xine. Did speaker-test again and there is sound. Maybe loading X activated something in nvidia driver which activated then audio to, and even after stoping X, that audio thing is still activated and can be used??

That's odd. I don't understand why running xine first would help.

Perhaps you could try compiling the very latest ALSA kernel driver code, and seeing if that makes any difference? Recently, some changes were made in the way the HDMI audio infoframes get set up for the chipset you're using.

I will try to compile latest ALSA kernel driver code, and will let you know what was the result at the end. Actualy it works now just fine, as on htpc start vdr and vdrclient scripts are executed and i get sound woring, but in command line interface before X and xine start speaker-test fail. And aplay test fail in both case. If i didnt mentioned I am runing Archlinux x86_64 distribution (used net install to have up to date packages).
