Playing audio with shell AGI

Could someone help me play a sound file with AGI in a shell script? I thought it was

But the phone just hangs up without playing the audio.

When I do

It spells hello world before hanging up so I know that works


Nevermind I’ve solved it by using echo 'EXEC PLAYBACK "hello-world" ""' instead but now I’m struggling to get this to take: echo 'Set(TIMEOUT(absolute)=2) ""'
