PA certainly supports 11025hz, u8, 1ch audio. I fear I cannot help you much to find out why exactly your specific application gets confused into thinking it wasn't supported.

Re: [pulseaudio-discuss] Sound works, still returns error alsa-util.c: Error opening PCM device
Dear Lennart, Thanks for the reply, PA version pulseaudio-0.9.10 alsa-plugins-pulseaudio-1.0.16 How do I know PulseAudio is running properly in the time of running the Java Application? How can I know abou it (How can I fix it?) This looks like borkage with ConsoleKit which would normally add the user that is active on the current console to the ACL of all devices.
