I can confirm this. The PBI in the Software Manager (version 2.2.2) works okay on my system. The PBI in testing (version 2.3.1) does not play audio files and is missing parts of the configuration menu relating to sound.
Since, so far as I know, the PBI module itself hasn't changed, I suspect this is a problem upstream or with the FreeBSD port.
For now I'd recommend using version 2.2.2, which is in PC-BSD's software manager.
