I just added the ability for op25 to send sound to the PulseAudio system in lieu of ALSA. This may or may not be a good thing depending on your Linux system as it seems some - notably RPIs of varying flavors - have issue with Pulse permissions, particularly it seems when you are running them headless. If you have working PulseAudio, you can tell op25 to use the pulse library by specifying "-O pulse" on the command line.

Advantages: may be less stuttery/prone to buffer underruns compared to ALSA
Disadvantages: permissions problems can sometimes be a bear to resolve on headless servers
