This function plays a sound from the info stored in the CSND shared memory (Offset3). The Channel ID argument decides which channel the sound will play in (4 channels available). If the specified channel is already playing, the Priority argument defines the priority of the sound. If the priority is higher, the playing sound will stop and the new one will start playing (smaller value means higher priority). Passing an out of bounds value to the Channel ID argument makes the CSND module become unstable or crash.
