Hello, if any one has ever used one of those live bootable linux cd and you have Ac'97 sound card, then chances are it wont work off the bat.

Unfortunetly, i have this problem.
If anyone has experience dealing with this sort of thing please let me know.

These small distros are great but there lack of configuration is a little disapointing..

Thankyou for youre time, most appreciated.

The AC97 codec is very common and you should be able to get it working....it's more down to the chipset that the sound card actually uses. You should be able to get this info with the /sbin/lspci command.

All of the live Cds I have tried my AC97 sound worked on.
With the exception of some of the smaller ones like BBCLinux but it is only about 50 megs

What happens if you start up something like xmms and try playing an wav/mp3 file? If it appears to play but you can't hear anything you should check the volume controls with kmix or aumix as the channels are often muted or at 0 volume.

If it comes back complaining about /dev/dsp, it is possible you don't have the correct module loaded. Try running the following command:
# modprobe ac97_codec
Do you get an error?
What is the output of:
# lsmod
FYI you can unload unwanted modules with the rmmod command.

Have you got a spare floppy disk? To save the output to a text file:
# mount /mnt/floppy
# lsmod > /mnt/flopy/result.txt
# umount /mnt/floppy

Depending on your distro the mount command may be different or not neccessary...I am unfamiliar with Flonix.

You can download the manual for your motherboard from here:
http://www.biostar.com.tw/support/manual/socket.php3?socket=478

Looking through there is a jumper which selects which codec to use, have you tried changing this? (Page 15 called JCODECSEL). I think it should be on pins 1-2. The manual also states that the motherboard...."...Supports popular operatin systems such as Windows NT, Windows 2000, Windows ME, Windows XP, Novel, LINUX and SCO UNIX"

wow, 3Dave you really went out on limb here :)

Thanks alot for all the info, i have downloaded the manual and am looking at what you described.

im not the sharpest tool in the shed, so i do have some more questions.

Im not not sure wich version motherboard i have of U8668-D, but they did provide an e-book of all the motherboards in one large file.

I am not quite sure what you are refering to
when you say JCODECSEL, is it a second sound codec. I canot find it in the manual but i do see something for tweaking something with the audio.

Is this it, it's under:
Motherboard Desciption:
---
Audio Subsystem: JAUDIO1/ JCDIN1
---

I would like to take youre advice and play with the jumpers and pins, but if you can kindly explain what i should do because i dont want to risk damage to the motherboard.

youve been such a big help already, ill understand if you dont want to anymore.


As for the output to floppy in a text file ill boot into flonix and try that out.
Ill be sure to send it in my next reply.
Thankyou

To answer your question from before regarding

Q: "What happens if you start up something like xmms and try playing an wav/mp3 file?"

A: Upon opening any video or audio file in Xmms or mplayer the video plays but the error message " it says No sound or something similiar nothing technical :("

I tried modifing youre command of sending output to a floppy in a textfile with modprobe.

I was unable so i used the debug switch..

I got alot of errors normally

What error do you get after typing "modprobe ac97_codec"? It should in theory load the module which will be listed when doing a "lsmod"....

here is the error:

knoppix@ttyp0[damnsmall] # modprobe ac97_codec
/lib/modules/2.4.20-xfs/kernel/drivers/sound/ac97_codec.0: create_module: Operation
not permited

/lib/modules/2.4.20-xfs/kernel/drivers/sound/ac97_codec.0: insmod /lib/modules/2

.4.20-xfs/kernel/drivers/sound/ac97_codec.0:
knoppix@ttyp0[damnsmall] #

im guessing the reason it did not work was because the contents are all on cd.

Try issusing one or all of the following before a "modprobe ac97_codec":

# rm soundcore
then
# modprobe sound
# modprobe snd
# modprobe soundcore
