emu10k1, kernel2.6, alsa and spdif out

Hi!

Has anybody succeeded in using the kernel 2.6 alsa drivers with an SB Live! using the spdif out? Everything my sound card outputs is pretty boring - nothing

My configuration:

# Module to load at boot-up (in this order)
#   (prefix a module with a ! to disable it)
#
MODULES=(!usbserial !ide-scsi snd-emu10k1 intel-agp 3c59x rtc bttv)

# /etc/modules.conf (for v2.4 kernels)

# Sound (ALSA)
alias char-major-116 snd
alias snd-card-0  snd-emu10k1
post-install snd-emu10k1 /usr/sbin/alsactl restore
pre-remove  snd-emu10k1 /usr/sbin/alsactl store
alias sound-slot-0 snd-card-0
options snd-emu10k1 extin=0x3fcf extout=0x1fcf

# Soundcard 1 (OSS Emulation)
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# Sound lookup entries for devfs support
alias /dev/dsp sound-service-0-3
alias /dev/sequencer sound-service-0-1
alias /dev/mixer sound-service-0-0

# Sample /etc/devfsd.conf configuration file.

[...]

REGISTER ^sound/.* PERMISSIONS root.audio 660
REGISTER ^snd/.*  PERMISSIONS root.audio 660

# Load ALSA sound when needed
LOOKUP snd MODLOAD
LOOKUP dsp MODLOAD
LOOKUP mixer MODLOAD
LOOKUP sequencer MODLOAD

[...]

I can use the sound devices without any problems, ie. I don't get any error while loading the modules or outputting any sound file. It's just that i can't hear anything. I haven't tested the normal not-spdif output, that one would probably work.

I have successfully used Alsa, emu10k1 and spdif-out several times before. Sometimes I had to enable the spdif out using alsamixer. But this time - no luck. I can enable/disable, tune up or down every possible combination and still no sound.

I'd appreciate any help!

Thanks!

Re: emu10k1, kernel2.6, alsa and spdif out

I don't know if that helps, but neither mplayer nor xine give me the option to use alsa as sound output... ?!

oh, i am blind - mplayer/xine is not compiled with alsa support. that does explain some things

Ok - I've got everything working now. I upgraded alsa-driver to the most current version (from alsa-project.org) and played again with alsamixer - now muting "IEC958 Optical Raw" and setting the PCM Volume to 0 did the trick. This is SO strange...

But everything works now - including AC3-Output with mplayer
