I've been having problems with my Pulse Audio server, and recently while investigating, I came across these error messages in /var/log/syslog:

Jul 20 09:16:40 mythbuntu pulseaudio[6555]: [pulseaudio] module.c: module-combine is deprecated: Please use module-combine-sink instead of module-combine!

Jul 20 09:16:40 mythbuntu pulseaudio[6555]: [pulseaudio] module-combine.c: We will now load module-combine-sink. Please make sure to remove module-combine from your configuration.

I looked in /etc/pulse/default.pa for any mention of module-combine, but did not see any. Also, I searched the web for elements of the error message and only got links to bug reports with vague discussions.

How do I get rid of this module-combine error?

The issue is in the 'paprefs' package, which on the 'Simultaneous Output' tab controls loading the 'module-combine' module. It has not been updated to use the 'module-combine-sink', and the 'module-combine' is now a dummy module that simply warns and then loads the 'module-combine-sink'.

You can change the module loaded by the paprefs setting by using 'gconf-editor' and changing 'system/pulseaudio/modules/combine', the 'name0' key should have 'module-combine-sink' value instead of just 'module-combine'.

In theory there are two bugs:

'paprefs' shouldn't be using 'module-combine'

'paprefs' should migrate to 'dconf'

Hope that helps.
