With xpra 0.8.6 (and probably a number before) on a CentOS 5.9 server xpra runs into a pulseaudio issue.
xpra is ready. pulseaudio: unrecognized option `--start' E: main.c: Failed to parse command line. 2013-02-27 18:55:58,250 Warning: pulseaudio has terminated. Either fix the pulseaudio command line or use -- no-pulseaudio to avoid this warning.
Some digging reveals that the CentOS 5.9 runs pulseaudio 0.9.10, which doesn't use the --start command, but rather starts simply by calling pulseaudio. Simply eliminating the --start from the commandline call embedded in the xpra.conf seems to solve the issue.
CentOS 5.x is too old to run pulseaudio (there are no official pulseaudio packages to begin with) so r2856 disables pulseaudio in the xpra.conf we ship so xpra should not try to start it. (this is done via an rpm specfile patch)
You can find updated RPM test packages in the beta area (build xpra-0.9.0-2)
Can you please check that xpra starts without errors so I can close this ticket. (this is not a major issue so I don't think I will apply this change to the v0.8.x branch)
There are no error messages related to pulseaudio with the 0.9.0-2 beta. There is also no sound, but that seems to be the point. Closing the ticket.
