Getting nasd working on KDE with Mandrake 2007

part of the Mandrake and Sound documentation

Ensure nas is installed on the server

In a console, run:

rpm -qa | grep -i nas

You should see both 'libnas2' and 'nas' listed in the output. If they either are missing, you can install them:

urpmi libnas2 nasd

Edit lts.conf

Edit lts.conf and ensure the following are available

       SOUND                     = Y
       SOUND_DAEMON              = nasd

Ltsp-sound package

Install the ltsp-sound package on the server. A description and download link for this package are available here:

http://wiki.ltsp.org/twiki/bin/view/Ltsp/Sound#NASD_and_ESD

if it is installed, you should find it in /etc/profile.d/ltsp-sound.sh

Install nasd for the clients

On the server:

cp /usr/X11R6/bin/nasd /opt/ltsp/i386/usr/X11R6/bin/nasd

Check sound card

Ensure the (pci) sound card is physically installed on the terminal by doing the following

cp /usr/bin/lspcidrake /opt/ltsp/i386/usr/bin/lspcidrake
cp -r /usr/share/ldetect-ls* /opt/ltsp/i386/usr/share/
cp /usr/lib/libldetect.so.0.6* /opt/ltsp/i386/usr/lib/

Run lspcidrake from terminal's shell and see if it lists a (pci) sound card. (To get a shell on the terminal, add 'SCREEN_02 = shell' to lts.conf. You can search this wiki for details.)

If you don't see the card and you know its installed, check for an ISA sound card. Documentation is available on this wiki.

KDE Sound Settings

Having logged in on the client, visit the KDE Control Center.

Under Sound: Sound System ensure the following settings are checked:

• Enable the sound system
• Enable networked sound
• Run with the highest priority
• Sound buffer=20ms (you want this as low as possible, but raise it if it's choppy)

under the Hardware tab select the audio device: Network Audio System

Troubleshooting

Using Konsole after logging into KDE on the client, try these checks:

echo $AUDIOSERVER

this should tell you the name of your terminal and the port nas is working on. No output indicates a problem.

auinfo

This should give you details of your audio server.
