Knoppix - ALSA

Hi, I just installed (after failing with about 5 distributions of Linux , dont ask me how I managed to go through all those without getting one to work properly, lol )
Anyway, I just got Knoppix installed and working, the only problem is sound. Now, running a 600E, I knew I would have problems with this, so I checked Google, but I couldnt find much help for Knoppix, I went into the sound and multimedia control centre, and selected ALSA as the Sound I/O, but when I click Apply, I get the message:

Error while initializing the sound driver:

device: default can't be opened for playback (No such file or directory)

The sound server will continue, using the null output device.

I am a Linux , so I dont really know what to do here, if anyone can help id really appreciate it

Thanks alot!

Yup. Sounds like you're not logged in as root when trying to get alsa going. Lost Penguin's got you on the right track.

su -
enter root password when asked
type M to mute/unmute channels, use arrows to navigate, Esc to exit
alsactl store

at this point ls -l /dev/dsp and make sure you've got permissions to use it and not just root. If it looks like:


then you'll probably need to change that, so:

chmod 755 /dev/dsp
ls -l /dev/dsp

It should now look like:


Should work nicely now as normal user. Hope this helps.

Hi, Thanks for responding.

After I su to root, I type alsaconf (I also tried alsaconfig), but it says:

bash: alsaconf: command not found

Any ideas?

Thanks for your help

Forget Alsa and try this it worked perfectly for me

Here is what I did

Open a shell and logon as root and type
insmod sound
insmod ad1848
insmod uart401
insmod cs4232 io=0x530 irq=5 dma=1 dma2-0 mpuio=0x330 mpuirq=9

this will load the correct drivers, however you will have to enter this everytime you reboot so if anyone out there has a script that will run these commands on boot I would appreciate hearing from you.

Update: I finally got the mods above to load at boot what I did was create a file with the above commands and saved it as cs4232 in the /etc folder and made it executable.

Then cd to /etc/rc5.d and ran

ln -s /etc/cs4232 S98cs4232

this created the symlink and I then rebooted the laptop and sound loaded on start.
