hi,
I'm trying to set up my EMU-0404 PCIe soundcard, but I get no sound.

the system recognizes the card:
output of lspci -vv -s 08:04.0:
Code:

08:04.0 Multimedia audio controller: Creative Labs SB0400 Audigy2 Value
Subsystem: Creative Labs Device 4005

   Flags: PMEClk- DSI+ D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
   Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME-
Kernel driver in use: snd_emu10k1
Kernel modules: snd_emu10k1


I've installed alsa-firmware and set the card as the default card:
cat /etc/modprobe.d/alsa.conf:
Code:

# Alsa kernel modules' configuration file.

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
##  ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
##  OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##

# OSS/Free portion - card #1
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
##  OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
options snd cards_limit=1

options snd slots=snd_emu10k1,snd_hda_intel
options snd_emu10k1 index=0
options snd_hda_intel index=1


I think the problem is the configuration of alsa?! If I run "alsaconf" I get the message that none of my cards is supported, but I get this message with the onboard soundcard too and even so I had sound.

output of aplay -l:
http://bpaste.net/show/100081/

when I run:
Code:
aplay /usr/share/sounds/alsa/Noise.wav

I get:
Code:
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
aplay: main:696: audio open error: No such file or directory


and:
Code:
speaker-test -t sine -f 440 -c 2

produces:
Code:
speaker-test 1.0.26
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Sine wave rate is 440.0000Hz
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

Hello,

From ALSA project, it seems 0404 support is still beta and not fully tested : http://alsa-project.org/main/index.php/Matrix:Module-emu10k1-fpga

well that sucks..!! :(

I've read that the PCI card is supported, for example: http://forums.fedoraforum.org/showthread.php?t=245159

I've tried to follow the instructions from your link, but while trying to configure the alsa-drivers with:
Code:
./configure --with-cards=emu10k1 --with-sequencer=yes

I get:
Code:

The file /lib/modules/3.8.6-hardened/source/include/INCLUDE_VERSION_H does not exist.
Please install the package with full kernel sources for your distribution
or use --with-kernel=dir option to specify another directory with kernel
sources (default is /lib/modules/3.8.6-hardened/source).


Do you think I should try it with pulseaudio?

In your aplay -l output, there is no device 1, only devices 0,2, and 3.
This is the problem? It does look like the kernel driver is not recognizing
something or misnumbering devices that it does recognize.

I only have an onboard hda-intel sound device at the moment to compare
with, but in aplay -l output it shows devices 0 and 1. device 0 is analog playback
and device 1 is digital playback.

The error message looks more like what one would see with a
misconfigured /etc/asound.conf or ~/.asoundrc, but I am no expert
on alsa setup, so that is only an impression from reading lots of alsa
problem reports.

(People still use the kernel's OSS support? I disabled it in the kernel
.config months ago, no negative side-effects with hda-intel or the
ice1724 driver. The only things that use alsa on my system are mplayer,
firefox, and alsa-utils tools like alsamixer and aplay.)

I think device 1 is the onboard-soundcard that I've disabled in the BIOS, because I've read one has to do that.

same on my system. the OSS support is enabled by default and I haven't heard that one should disable it.

I disabled OSS in the kernel .config when I was trying to figure
out some alsa problem with a few pci soundcards. (It did not
make any difference, but the soundcards eventually worked
without it, so I left it disabled.)

I do not know if alsa would assign "device 1" to onboard sound
disabled in BIOS. How would it even know it is there?
(You probably don't have an /etc/asound.conf or ~/.asoundrc,
either, I guess, so alsa would be using a default configuration.)

The fact that your soundcard actually appears in aplay -l
output is a good sign, though. The kernel finds it, alsa knows
it is there. It should be possible to find out what slave device
it is trying to open and failing. (It is just that when I have seen
messages like that in people's problem reports, an asound.conf
or .asoundrc file was always actually redirecting the output
through what alsa calls a "slave device".)
