edited modules/no sound


Hi everybody !

I have compiled alsa to get some sound from an MSI mainboard

The above is using VT8233A chipset, the sound is using ALC650 chip and i have found in the user's guide , that direct sound is AC97.

My modules are :

alias usb-controller usb-uhci
alias sound-slot-o via82cxxx-audio

alias char-major=116 snd_cards_limit=1
options snd snd_major=116 snd_cards_limit=1

alias snd-card-0 snd-via8233
options snd-via8233 snd_index=0 snd_id="via8233"

alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-0ss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss


iIf i try " lsmod " this is what i get

snd 34272 0 (autoclean )

via82cxxx_audio 18144 1 (via82cxxx_audio)
uart 401 6356 0 ( " " )
ac97-codec 9568 0 ( " _audio uart 401 )
soundcore 4068 4 ( " _ audio sound )

Any idea of how can i get some sound ?

Cheers

Hello dorian , Aumix was used just after compilation and sound channels were unmuted as required ... but i don't get any sound !!

Can you see by the above data that everything is as it should be?

Are my edited modules right !! ( i mean how can i be sure )

Cheers.

Sorry, I am not mandrake familiar. In fact I am finding a troubles in reading your modules.conf.

See at my config:
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-via82xx
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# 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

My modules (located in /lib/modules/2.4.20/sound) :
snd-ac97-codec.o
snd.o
snd-via82xx.o
soundcore.o

So the relations between aliases and module names are clear for me. Hope it helps.

Hello Dorian, i really appreciate your replies...it helps, whatever the results in the end ;-)

Just a question : should i leave a blank betweens lines?

You says above " modules options should go there " what if i edit

alias snd-card-0 snd-via8233... just below
alias snd-slot-o snd snd-via82cxxx-audio
without any blank in between ?

The blank lines and line starting with '#' makes the file more readable, you can cut them if you wish.

Hi dorian,

Did not noticed before but have the following message at boot:

/lib/modules/2.4.18-6mdk/kernel/sound/acore/snd.o invalid parameter

Any idea?

Look, I do not know how currently your your modules.conf looks like and which is the name of all the important modules in /lib/modules/... dir.

WIth the message you have got you should look at the modules.conf file and find the lines with relations to 'snd'. I mean the lines not only with the phrase 'snd' placed directly in them but all which are chained with alias names.
I believe you'll find the extra parameter which is invalid.

For example line " alias snd-slot-o snd snd-via82cxxx-audio" is strange for me
1. snd-slot-o: 'o' or '0' (zero) ?
2. why there are so many tokens? the known for me 'alias' syntax 'alias xxxx yyy' consists only 3 tokens.
It looks like you created the alias for 'snd-slot-o' with 'snd snd-via82cxxx-audio' so the phrase 'snd-via82cxxx-audio' is this invalid parameter for 'snd' (?)

Sorry. I can't help you much more.

Hello dorian

sorry, part of my reply was misleading.

Was 0 (zero) not o and snd should only have appeared once.

Sorry again.

I have checked modules once again, and as those came with Alsa readme files, i don't see any mystake.

There is another message at boot , that says

invalid parameter parm_snd_major

But once again modules came from Alsa.

How can i be sure, i am editing the right modules ?

I tried command" lspci -v " and only found ac97 audio controller, no trace of via8233 as per the user's guide.

When i try to modprobe via8233 the message is it cannot be found, when i try to modprobe ac97, i can find it in the list when command " lsmod " is launch, but doesn't make much difference in the end.

Also as you can see above soundcore is related with number 4 in lsmod ... what does it mean ?

You probably have got the same mobo as mine.
Use 'cat /proc/pci | grep audio' to obtain the info about audio.
If you make sure that there is 8233 check you have the same modules as I have got. Next use my setting in modules.conf.
BTW:
1. AFAIR using ALSA you need the kernel to be compiled with soundcore only without the other settings.
2. When you compile the ALSA you can use './configure --with-cards=via82xx'. This way your directory with sound modules will be reduced to the interesting ones.
