I'm not sure about periodic generators, but using some shell scripting
and "raw" audio formats for IPC (no EOF/file-length metadata exchanged
between processes), it's easy to play a file in an infinite loop without
reopening the audio output device (which causes audible gaps).

You need to specify a common raw format for the exchange,
and setup a pipe:

# customize FORMAT to match your input file
FORMAT="-t s32 -c2 -r44100"
play $FORMAT "|while sox input.wav $FORMAT -; do :; done"
