Alsa - cs46xx driver seems to work but no sound


Hi there,

All is in the title.
Alsa (0.9) starts and stops with no errors. When it starts i can hear a little "boom" from my speakers showing me it works (it's the same when I change the global volume in aumix). In aumix all volumes are set to 100
But when I try to play a sound, nothing goes out from my speakers. I have tried to play a mp3 with xmms, kaboodle, music123.. The button "test sound" in KDE's sound configuration tool does nothing either.

Sound card : Hercules Fortissimo II
Kernel : 2.6.1
Distrib : Debian
A piece of my modules.conf :
#...
# This file was automatically generated by alsa-base's debconf stuff

alias char-major-116 snd
alias char-major-14 soundcore

options snd major=116 cards_limit=4

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
alias /dev/dsp* snd-pcm-oss

alias snd-card-0 snd-cs46xx

alias snd-slot-0 snd-card-0
alias sound-slot-0 snd-slot-0

### update-modules: end processing /etc/modutils/alsa
#...

Thanx !

I am not familiar with aumix. When I have installed Alsa I usually run amixer from the command line before starting to use any graphical programs to set the volumes:
amixer set 'Master Digital' 95% unmute
amixer set 'PCM' 95% unmute
alsactl store


Also make sure your user has access to /dev/dsp0:
chmod a+rw /dev/dsp0
chmod a+rw /dev/mixer0

Thanx for answering,
but i have found alone a solution
I installed manually the latest version of alsa as described here : http://www.alsa-project.org/alsa-doc...&module=cs46xx

After that, there was no sound either .. but I tried another program instead of aumix : the KDE's mixing tool Kmix.
I increased the equivalent of "pcm volume" (the wave symbol) and the music played oh
I think as you it was aumix that bugged

(sorry for my poor english)

Now i have another problem : my headphones produce no sound (even if their volume is set to max)

How are your headphones connected to the sound card? If they use another output than the regular speakers you might have to increase the gain on another channel (not PCM since they controlled the speaker output). I suggest you try amixer or alsamixer.

It's the same with amixer and alsamixer

I have browsed a few forums and it seems that i'm not alone in this situation
The problems are :
- headphone volume controls rear speakers volume
- there's nothing to control headphone volume

I just have to wait for a new version of cs46xx...

Hoho, i found a solution

I hadn't seen we could select a soundcard and a subdevice in ALSA's output plugin configuration in XMMS
So i chose the subdevice "Rear Speakers" for my card and i plugged my headphone into the rear speakers' output
It works ^^ (just a little problem of saturation that can be cleared by decreasing the "DAC" volume (dunno what's this) in alsamixer)

Thanx,
bye
