[alsa-devel] [bug] SPDIF (digital-out) not working on NForce4/CK804
Hi all,
Sorry to bump in like this, but I was advised to submit a bug-report for the ALSA-drivers on my HTPC: no sound comes through out of my AVR when I select the digital output through SPDIF (TOSLINK).
The relevant parts of my HTPC are as follows: * CPU: Athlon64 X2 3800+ * Motherboard: ASUS A8N-SLI Deluxe motherboard (BIOS 1805) NForce4 with CK804 sound (relying on a Realtek ALC850 chip) * RAM: 2x 512 MB DDR-400 * GPU: nVidia Geforce GT240 (which carries a HDMI port and uses the snd- * Receiver: Marantz SR7500 (supporting both Dolby Digital 5.1 and DTS decoding), connected to motherboard's SPDIF TOSLINK port (optical) + JBL 5.1 speaker-set * OpenElec 4.2.0: Kernel 3.16.3, Alsa 1.0.28
Symptoms: Speaker-test does not produce any sound. Command used is as follows:
speaker-test -c2 -r 48000 -D hw:0,2
No sound either from other applications (such as XBMC 13.2).
SPDIF worked flawlessly on the exact same hardware & connections using Win7/XBMC. Sound does come through the SPDIF when I use hw:0,0 (= analog device).
Things tried (none working): * Blacklisting snd-hda-intel (= HDMI from my GPU) to make sure CK804 is the only sound chip visible.
* amixer set 'IEC958 Playback AC97-SPSA' Playback 100% unmute
* Contacted XBMC developer via IRC for investigation: concluded that problem would be with kernel driver, advised to create this bug-report.
* Tried another distro (Ubuntu from XBMCBuntu 13.0).

I am willing to test or provide further details where needed. I am new to Linux, but am a developer myself (C#) so I know how to look up some info... Hoping I haven't offended any of you with this post.
THNX, Bye!

Hi,
Command tried:
speaker-test -c2 -r 48000 -D iec958:CARD=CK804,DEV=0
Still no sound coming through AVR...
For the sake of completeness, I provide a new alsa-info.sh output: http://sprunge.us/ZWLF (I blacklisted the snd_hda_intel this time just to be on the safe side).
The git-link below ( http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/NFORCE.c... ) seems to point to the .conf for nForce2/3; min is a nForce4 (don't know if nForce4 is supposed to use this same .conf).
THNX already, Bye! _____ *Gilles Hemberg* /gilles.hemberg@gmail.com/

Hi,
It works!
Solution (in OpenElec 4.2.0; settings on other distros would be similar): * Create custom asound.state in /storage/.config/ with the following contents: http://sprunge.us/SiHH (this state-file will, among other things, unmute the appropriate mixer controls, set proper output formats, ...).
* Load the above state file with the following command:
alsactl nrestore 0 -f /storage/.config/asound.state (replace the "0" with the card-number corresponding to CK804 on your system)
You may want to add this command to a custom autostart.sh in /storage/.config/ so the state is restored on every boot.
* Create intel8x0.conf in /storage/.config/modprobe.d/ with the following contents:
options snd-intel8x0 spdif_aclink=1 (I am told that this above setting depends on the specific motherboard, so this may not work for everyone: it does work on my ASUS A8N-SLI Deluxe)
This was the final setting that solved the issue for me. I did try this setting before, but it seems that some sources on the Internet had this mis-written as "options snd-intel-8x0 spdif_aclink=1" (notice the extra dash).
* In XBMC, select the SPDIF out as both the audio-device AND the passthrough device.
I wanted to post the solution that worked (in my case) here so others may be able to benefit from my experience.
Thank you very much for your input Raymond: really appreciated!

You can add pci subsystem id into spdif_aclink_defaults

Does it use slot front left and front right slots for pcm playback?
Does it use spdif left/right slot for ac3 passthrough? default for alc850 after cold boot
Can it get signal from the other two setting : rear left/right slot or center/lfe slot?
