Unhappy no sound with kernel 2.6.2 and alsa


hi there.
well i managed it to load my sound modules somehow. now when i am starting kde i get no sound... (before i got a error message /dev/dsp not found but after reinstalling alsa it worked).

i unmuted my volumne. xmms is playing but i cannot hear any sound. everything works fine it seems, ecxept there is no sound coming out of the speakers.

ya, i booted with XP and there IS sound (so no speaker problems)

before with 2.4.22 everything was working fine.

any suggestions?

some output:

have you rebooted since unmuting, if so, did you run alsactrl store, to save your default volumes?

heya. thx for answer.

ya i tried to reboot. and yes i stored the volumes and checked it after reboot. its weird.
everything behaves if sound would work (kontrolcenter is telling me dsp is in use and so on when playing xmms and trying to update the arts settings).

oh and i've checked the whole forum and searched for an answer... i couldnt find anything suitable. i had problems with installing before.
does anyone know which packages (debian) i have to install? i was installing everything containing the word "alsa"...

have you tried multiple file types, i.e. mp3, ogg, etc. to see if it is a file type recognition problem?

well it seems to recognize my mp3s. its telling me the name of the singer, title, length and so on and i am able to see the equilizer working.
when starting kde its playing smth different than mp3 (wav i think) as well i was testing the sound with alsaconf - nothing. oh and trying the test sound of kontrolcenter :-) everythinig the same result. kmixer looks working (no X in taskbar) and when opening everything is set to max.

additional info: could it be that 2.6.2 wont work together with alsabase 1.0.1-1?? i am using driver modules from kernel 2.6.2 and alsabase, utils, etc. from sarge/sid?

you may have hit the nail on the head. i took a look at the alsa site, and, the most recent driver packages 1.0.2c appear to have fixes for 2.6.x kernels. hope that helps.

If you installed the alsa stuff via rpm, I believe that there is a specific kernel-alsa-"your kernel version number"-i686.rpm
I think those kernel-alsa rpms are indeed kernel specific.

PEACEDOG wrote something about patches for 2.6.2? where do i find them at alsa-project?

btw... i was installing the drivers from the kernel (they were included) and installed alsa-utils and the other stuff later.
this did not work.

now i recompiled the kernel WITHOUT alsa support but WITH soundcore. ill try to install .deb packages again. if this wont work either i will install alsa without deb packages... sigh. will be messy but if it works...

well i found out that OSS is installed as well... maybe this is causing the problems. right now i am running with OSS and it works. cannot mute / change volume within kmix though...

i will try to deinstall OSS and install ALSA. maybe this will help

Mate,

I went through all this drama with debian, 2.6.2 and alsa the other day. I managed to get alsa going only by installing several alsa packages via apt-get. I thought this sorta defeated the point of having it compiled into the kernel, but anyway.

Well alsa was working for xmms and mplayer, only after selecting for alsa in preferences. General apps were not producing any sound, eg games, or flash running in a browser.

What I read, alsa seems to be a major pain to configure.

I solved my hassles by reconfiguring the kernel with oss but not alsa, and running good old sndconfig.

Now I have perfect sound.

thx mctavish,

if no application is using alsa yet i wont install it (yet) i guess.
thanks for information...

btw... any experience using the OSS EMULATION optin within the kernel? did you try this or did you use the OSS option for itself?

I had the same problem yesterday using Slackware, end up recompiled with only sound support and installing the packages from source using the packages from alsa and the instructions on the site for my particular sound card. Only differemce now than from using 2.4 kernel is I have to modprobe my soundcard (snd-emu10k1) at boot to get it working rather than leaving it commented out in the Slack rc.modules file.

Don't know anything about OSS emulation, I just ignored alsa altogether and compiled in standard oss.

Looking_Lost, I also have a soundcard that uses that module (Soundblaster Live).

I used a command called modconf which added this line into my modules file to load it up at boot:
emu10k1

This may help you, I don't know.
