symbol export missing: pa_encoding_from_string

[Chris West]

This specific release of libpulsecommon-11.1 is missing the symbol `pa_encoding_from_string`.

This was fixed upstream: https://bugs.freedesktop.org/show_bug.cgi?id=103806
This has a Debian bug open, but I suspect it's been fixed by bumping major version: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=882029

This results in unexpected:

Forwarded from #882029. This function is found in format.h but it not exported in map-file and thus unavailable on most (all?) linux systems. I don't know if the function is supposed to be exported, or maybe it should be private instead.

#882029: https://bugs.debian.org/882029

[Tanu Kaskinen (tanuk)]

I'm 99.3% certain that it's supposed to be exported. It's documented, and internally it's only used in format.c, so if it isn't meant to be exported, then the declaration should be removed from format.h since it's not needed.

[Tanu Kaskinen (tanuk)]

The patch is now in master.

Thanks for the detailed bug report. It looks like the fix first appeared in PulseAudio version 12.0. So "Fix Released" for Ubuntu 18.10 and nominated 18.04 to receive a fix.

[Sergey "Shnatsel" Davidoff (shnatsel)]

I am still experiencing this on latest Bionic. So apparently the fix is not really released?
