Hold Music and Prompt Overlapping

Hi there. On a fresh install of Asterisk, suddenly the hold music is starting at the same time as the welcome prompt. It shouldn’t start until after the first prompt is finished playing back. Does anyone know what can cause this?

Thanks

[Edit] Example:

app.playback(“welcome”)
app.startmusiconhold(“holdMusic”)

Turns out uninstalling asterisk-dahdi resolved the issue.
