Enables actually using sound_play node added in #332 .
On most systems, other libraries are needed, but it doesn't make sense to make them dependencies of the festival package:
alsa-plugins
is needed.ln -s /usr/lib/alsa-lib/libasound_module_pcm_pipewire.so /home/deck/mambaforge/envs/ros_env/lib/alsa-lib/libasound_module_pcm_pipewire.so
(there is no pipewire package on conda, but as Arch is a rolling distro, the versions from conda and Arch are not too distant, so this hack works).
