Hooray! This turned out to be the key. My problem is solved. Here, for the record, is a short summary. I wanted to use ltsp-localapps on the thin client to do some things that require the sudo command. So I used copies of these files from the server to overwrite the ones in /opt/ltsp/i386/etc: /etc/passwd /etc/shadow /etc/sudoers /etc/sudoers.d/README Then "ltsp-update-image --arch i386" gave me a chroot in which sudo would work. What went wrong? My list of new files for the chroot missed one: /etc/group It was the log file on the client (/var/log/syslog) that alerted me to a discrepancy between the GID for user "pulse" declared in /etc/passwd (which I had replaced) and /etc/group (which I had forgotten). Refreshing /etc/group and updating the image has me enjoying audio again. [Aside: In an earlier response, I incorrectly echoed one of Jan's statements. The pulseaudio server should run on the thin client, so it can drive the speakers, but it should *not* run on the LTSP server. I apologize for letting this misconception leak into the archive.] Warm thanks to David, Richard, and especially Jan for their generous and helpful guidance! ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
