With #ltsp help, I have identified that this problem is not unique to rdesktop, but general to padsp. If, for example I run... $ padsp speaker-test It fails just the same as above. Indeed, if I specify oss as the local sound driver... $ padsp rdesktop -r sound:local:oss SERVERIP ...sound works fine, but if leave "oss" out, or specify "alsa", then it bombs out. Clearly alsa is the problem, and yet I know alsa is installed and working, because that's what's set in my KDE control panel, and my sound is working just fine in Linux. I am thoroughly confused and hopeful that this will all make sense to someone, if not to me.
