sound not working in slackware9.1 with AC'97

andy753421 · 04-23-2004, 05:39 PM

i havent been able to get my sound to work (at all) im running slackware 9.1 with an AC'97 sound card built into my motherboard (AK39N made by www dot shuttle dot com) at first it says i had something wrong with the alsa something or another and it told me to go check alsamixer and when i did everything was turned to the lowest and muted, so i turned those up, saved and re-booted. and i still get nothing, it wont even play the test sound from control center. sorry for asking about this again i know people have asked about this stuff a lot but i couldnt figure anything out from previous post/google. in explanations please assume im a total linux noob.

Could you be any more specific about "alsa something or another"?

If you reboot, alsa will start up muted. To get the levels set, you need to give the command (as root) `alsactl store` after you get the levels set where you want them. Then add `alsactl restore` to your /etc/rc.d/rc.local file.

You also don't mention what kernel you are running or if you compiled it yourself.

What do you get when you enter the command ` /sbin/lsmod`?

Are the speakers turned on? Not trying to be insulting. I just tonight realized that a problem I was having with sound on a VIA EPIA board with AC97 sound was that I hadn't turned up the speaker volume. (Hey, it happens...)

andy753421 · 04-23-2004, 06:29 PM

the kernel is 2.4.22 um as for the alsa im really not sure what exactly it said, i believe it was something like the alsa drivers arnt tunred on or something, but when i did alsamixer it (and then i also did alsactl store) it didnt give that message any more, i didnt do the alsactl restore but i dont think that matters because when i re-boot the volume levels and everything stayed where i put them. yea im sure the speakers are on, believe me ive checked that many time hopping it would work.

When i type /sbin/lsmod it give me

Did you run `alsaconf`?

Here is what I get when I run `lsmod`:

As I said, I was having problems with getting sound out of that box. One of the problems I had was the volume on the speakers themselves. Don't know if it was the source of the problem or not, but I compiled and installed the oss modules. If you are missing a module that I have, then I have overlooked it.

hm ok thanks a million i just had to run alsaconf and that sorted everythign out

kenji1903 · 05-17-2004, 01:27 AM

Hi guys!
I've just upgraded my RHL9 kernel to 2.6.3 and I don't think I caught eye one any AC'97 thingy... my mobo's MSI KT6V with a built in sound chip, similar to the ones you're using...

Can anyone here lend me a hand?

daemonTED · 06-13-2004, 03:38 AM

heh, yeah thanks guys. alsaconf sorted out problems i was having too

kenji1903: might be able to help, but will need some more info such as the output of lspci to start with, although personally i know virtually nothing about RH, so might not be much help at all

anyway, if you post the outputs of things like lspci and lsmod, i am sure someone will be able to help you, maybe even me

(i use debian, and have never used redhat :P)

hi,
i also encounter similar problem, after manually compiling kernel (version 2.6.12 with built-in module included. set CONFIG_SND_AC97=m )
the env i use is debian sarge (stable) 3.1 r0a.
it works fine in default kernel version 2.4.x.
the outcome of `lsmod | grep ac` is as follow:

Code:

snd_ac97_codec         83064  1 snd_intel8x0
snd_pcm                95432  2 snd_intel8x0,snd_ac97_codec
snd                    51512  4 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer

and
`lspic | grep audio` is

Code:

0000:00:1e.2 Multimedia audio controller: Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)

what should i do in order to get my audio work??
i appreciate any suggestion, sincerely.
