yes and there is no sound
i have unmuted and tried to solve this with alsamixer but no way it did not help

here is my alsa conf

alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-via82xx # i have added this manually to suit my card
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-0-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
options snd cards_limit=1

and in kde after /etc/init.d/alsasound start the system got so slow even if the mouse was moving slowly

when i /etc/init.d/alsasound stop the modules are
bash-2.05b# lsmod

i have tried the gentoo linux alsa guide

2. Installation

Gentoo USE flags

To compile programs with ALSA-support, be sure to add alsa to your USE-variable. However, several tools don't support alsa yet, and require OSS. ALSA provides OSS-emulation if you define oss in your USE-variable before you start.

i did not understand this and did not do anything in that step

i have also tried
/usr/src/linux/scripts/MAKEDEV.snd
no sound again

and i have seen this is a topic here
i know that the alsa is built in my kernel but i have tried it unconciously

ACCEPT_KEYWORDS="~x86" ALSA_CARDS="via82xx" emerge alsa-driver
and i think it gave an error at the end

ps: i was using topologilinux 4 and the sound just worked wih
modprobe snd-via82xx or something like that on kernel 2.4.22 i think those drivers were oss
can i use oss in kernel 2.6.3 ? i have seen them in the kernel config but said deprecetad (by alsa of course)
what should i do to fully remove alsa and add oss to my linux

ps: how can i see the card and tuner database for bttv to configure for my card and is there an automatic tools for this for gentoo like gcbttv

[VeSCeRa]

and in kde after /etc/init.d/alsasound start the system got so slow even if the mouse was moving slowly

then i do
bash-2.05b# /etc/init.d/alsasound stop
* WARNING: you are stopping a boot service.
* Unloading ALSA...
* Storing ALSA Mixer Levels
* Unloading modules [ ok ]
bash-2.05b#
then the mouse and system works on normal speed but this time kde says the sound device can not be opened

[cerealito]

I had the same problem with the same sound card, kernel 2.6.1 and ALSA.
after some reading, i got it running stopping the existing ALSA, and then

Code: Select all

env ALSA_CARDS='via82xx' emerge alsa-driver

(not snd-via82xx or snd-card-via82xx)
then rebooted and everything went fine.

I've got this in /etc/modules.d/alsa

Code: Select all

##  ALSA portion
alias snd-card-0 snd-via82xx
## alias snd-card-1 snd-ens1371
##  OSS/Free portion
alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##

Everything was documented in the gentoo-alsa how-to, except the ALSA_CARDS='via82xx' thing...

Hope it helps.

[VeSCeRa]

thanks for your excellent comment
can u help more

afer emerge'ing with that command what steps should i take?

[VeSCeRa]

ohhhhh thanks maaan
i was using oss after that alsa thing
and after emerge the alsa sound worked perfectly
thanks very much

ps:i disabled the alsa sound in kernel config when i was trying the snd-via82xx module and enabled the oss and was using the snd-via82cxxx modules now alsa works perfectly what should i do in the kernel config should i disable oss and should i enable alsa there?
