Upgrade valgrind *TODAY*.  The current version is valgrind-3.21.0.
Valgrind-3.7.0 was released in November 2011: commit 261bffdb4c2a52014ee10b4d68a75db0ec5834e60.
It is a waste of everyone's time to chase "not implemented" in software
that is over 11 years old and has been updated frequently since then.

Fix your bugs:
1. README.md:  libao-devel must be installed, else "#include ao/ao.h" fails.
2. gcc ./src/utils.c -c -O2 -Wall -pedantic -Wextra -Wc++-compat  -fsanitize=address -g
./src/utils.c: In function ‘handle_sound_name_queue’:

3. libasan is required.
4. libasan must be first in the list presented to /usr/bin/ld, else it does not work correctly:
    "ASan runtime does not come first in initial library list; you should
     either link runtime to your application or manually preload it with LD_PRELOAD."
