SB Audigy 2 value IO out

mrchaos · 05-03-2005, 07:10 PM

I've seen some posts in many different places that dance around this question, but no definitive answer has been posted. I use a Creative Audigy 2 value PCI soundcard, and I want to use the "Digital IO" jack in the back to connect my computer to my stereo receiver. Here's what I've done to attempt this:

- ran alsaconf, detected my card as "Creative Labs: Unknown device 0008," uses module "emu10k1"
- alsamixer -> turned on the mixer labeled "Audigy Analog/Digital output Jack" and turned off the mixer entitled "Optical raw"
- edited modprobe.conf to include the phrase options snd-emu10k1 extin="0x0fc3" extout="0x1f0f"

I tried some other options from sites such as:
http://lists.suse.com/archive/suse-l...-Jan/1772.html
http://alsa.opensrc.org/index.php?page=emu10k1
But I'm running Slackware 10.1, so half the stuff from other distros flat-out does not work. I'm running ALSA version 1.0.8.

ALSA recognizes this chipset:
Card: Sound Blaster Audigy2_Value
Chip: SigmaTel STAC9750/51

Any help would be greatly appreciated

Here is my emu10k1.conf configuration file:

##
## This file is used to configure emu10k1's emu-script
##

CARD_IS_5_1=yes
USE_DIGITAL_OUTPUT=yes
ENABLE_TONE_CONTROL=yes

# Note, it's safe to say yes to the next option even if you're not going
# to use it. When this option is enabled, the driver can autodetects AC3
# data and behaves normally with normal audio.
# (Saying yes causes some of the soundcard's resourses to be used up)
AC3PASSTHROUGH=no

# Change this to yes to enable the Livedrive midi port and IR remote
# control.
ENABLE_LIVEDRIVE_IR=yes

# Most Lives have their analog front signals inverted. If you have
# problems with your setup (low bass), try changing this to 'yes'. (This
# option has no effect with digital setups)
INVERT_REAR=no

#Multichannel playback (for 4 - 6 channel setups)
MULTICHANNEL=yes

# On 5.1 cards in multichannel mode, should the multichannel data be fed
# to the sub as well? You probably don't want this if you have a
# speaker set like the DTT2200 which already feeds all channels to the
# sub in hardware.
ROUTE_ALL_TO_SUB=no

# By default, the front analog channels have a +12dB boost applied to
# them by the AC'97 mixer. If you encounter clipping, or find that the
# volume of the front speakers is too high in a multichannel setup, try
# changing this to 'no'.
ANALOG_FRONT_BOOST=no

# Surround
##################

# Some wavs, or mp3 are surround sound encoded the next two
# options can be used to decode these in hardware.
# (select on or the other, not both)

# passive matrix surround decoder
SURROUND=no

# Active matrix surround decoder
PROLOGIC=yes

# Extra Inputs
#################

## This connector is mounted on the card itself
ENABLE_CD_Spdif=yes # Volume control is 'Digital1' in aumix/gmix/kmix

# The next four inputs are found on Livedrives, some of these may also
# be inputs on the older add-on daughter cards.

ENABLE_OPTICAL_SPDIF=yes # Volume control is 'Digital2'
ENABLE_LINE2_MIC2=yes # Volume control is 'Line2'
ENABLE_RCA_SPDIF=yes # Volume control is 'Digital3'
ENABLE_RCA_AUX=yes # Volume control is 'line3'

Somebody?????? :-(

I got an answer thanks to jcdutton on creative@irc.freenode.net. Apparently the answer -- short and simple-- is you can't configure the digital output for audigy 2 value cards in linux. ALSA 1.0.8 doesn't support this. But he did suggest that I try using the new alsa revision 1.0.9rc2.

I have an Audigy 2 Value running Gentoo kernel 2.6.11-gentoo-r8. The PC is connected to a dolby digital amplifier via coax SPDIF. I downloaded alsa-drivers, alsa-libs and alsa-utils all version 1.0.9rc3. Still no sound playing a .wav file from aplay. xine now clicks a few times over a one second period when playing a DVD when the sound starts (on this DVD when the menu comes up after all the warning screens), but otherwise no sound.

Is there some secret using alsa 1.0.9? Does it need a newer kernel (I doubt it since the sound support is compiled separately and loaded as a module)? Is there some secret incantation in alsamixer to enable all sound to come over the SPDIF?

mrchaos · 05-20-2005, 04:19 PM

guyknur: no, rev. 1.0.9rc3 does work on 2.6.11. I had the same problem with the coax output (that's what I meant by the digital output). I was told that it was impossible to use the coaxial output for an Audigy 2 value in Linux. However, for some odd reason, the damned thing simply started working today. The truth is that I have absolutely no clue why this is, since I'm sure that I made no changes between now and when I first tried to configure the card. To get yours to work, make sure you disable the option "Optical Raw" in alsamixer. The digital coaxial output will NOT work with this option enabled. If this doesn't work, I'm not quite sure what else to say... Either way, I'll post my modprobe.conf and others... see if they help you:

If you remove /etc/modprobe.conf and run "generate-modprobe.conf /etc/modprobe.conf" it might work for you. Otherwise I'm not sure what modules (besides emu10k1) the audigy 2 can utilize.
