[linux-audio-user] Using DeMuDi

[derek holzer]

Darren,

the Sarge version of Demudi is unofficial [actually, the source below is 
Guenter Geiger's own development version], so use with caution. try it 
by adding this to your apt-get sources:

deb http://devel.demudi.org/demudi sarge demudi
then 'apt-get update'

if you want to use the Demudi kernel, you will still have to do a few 
things:

1) first, after upgrading to Sarge, 'apt-get install demudi-base'. once 
the Alsa, Jack and kernel packages have been installed, add the line
initrd=/initrd.img
to  your lilo.conf BEFORE rebooting [don't forget the 'lilo' prompt 
after this...]

2) mkdir /dev/shm

3) add the following line to /etc/fstab:
none /dev/shm shm defaults 0 0
[this is a virtual file system which Jack uses. you will run Jack as 
user, not as root. if you run it as root, it will make a logfile in 
/dev/shm that will jam up everything, and you will have to remove this 
file to continue.]

4) reboot. if all goes well, you will boot into Demudi kernel, and then 
you can 'apt-get install demudi-soundapps'.

5) Demudi uses info from an app called Discover to configure your Alsa 
settings for your soundcard. this wasn't too reliable last I checked, so 
if Alsa doesn't keep your soundcard info after each reboot, I recommend 
you configure it manually, with info from the Alsa soundcard matrix on 
the Alsa site, in the following places:
/etc/asoundrc
/etc/modutils/aliases
look here for more tips on this if you don't know how to do this:

good luck,
Derek
