Is there a recent guide to LTSP sound troubleshooting?
My previous Ubuntu 8.04 installation on an HP dc7800 server
with an HP t5710 client worked quite well. But after upgrading
to 9.04, sound stopped working.
When playing a youtube video in Firefox, I get about 30 seconds
of sound, then the audio stops. No more sound until I reboot
the thin client.
I have no idea where to look. Here are some random things I've
looked at based on what few troubleshooting hints I've found:
server$ cat /var/lib/tftpboot/ltsp/i386/lts.conf
