Symbol ao_file_extension not found

[rokf]

I'm trying to run examples/ao_live.lua which crashes with the message

lua: error loading module 'ao' from file '/usr/local/lib/lua/5.1/ao.so':
  Error relocating /usr/local/lib/lua/5.1/ao.so: ao_file_extension: symbol not found
stack traceback:

I'm using Alpine Linux with libao-1.2.0-r1. Any idea what could be wrong since the version is the most recent one (1.2)?

I found this bug: https://trac.xiph.org/ticket/1841 but that says it should be fixed in 1.2.0 Can you run nm -D -C --defined-only /usr/lib/libao.so? What I get:

0000000000000000 A LIBAO4_1.1.0
0000000000000000 A LIBAO4_1.2.0

If not there then i think file a bug against libao on the alpine tracker?

Yup, it's missing. Getting:
