The "sleep 1" trick fixed the client I'm currently playing around with. >As for getting modules to load, you must enable sound and the necessary >modules in lts.conf.

Pre-loading soundcore.o and sound.o was included in the original ltspsound tarball. I'll look at testing/fixing that. BTW, since LTSP v3.0 includes full module dependancy info, I altered the ltspsound scripts to use modprobe instead of insmod. This allows one to be lazy and only specify the last module that needs to be loaded ;-) (and does not break things if you specify every module that needs to be loaded). >Unrelated to your problem but of note was that the default sound volume >is quite high. I set in rc.sound "aumix-minimal -v65" to prevent the >clients from coming up too loud. As far as I know, there's no good way to deal with this besides editing the default volume by hand. Remote mixer capabilities sure would be nice. The other major problems I've seen include some programs crashing due to nasd's LD_PRELOAD (xboard is a consistant example) and DNS woes. I'm not sure what to do about the LD_PRELOAD problem, writting wrappers to unset LD_PRELOAD would work but is messy. The DNS problems would probably be fixed by altering the scripts to use IP address only. Hey Andrew, are you still working on ltspsound? -Eric >-----Original Message----- >From: G.
