If it doesn't happen when other applications are playing audio, it probably only happens when the device suspended prior to speech-dispatches starting to play it's audio. Reducing the suspend timeout from the default 5 seconds to 1 or 0 seconds may help with reproducing the issue more frequently. Setting the timeout to 0 seconds can be done by giving argument "timeout=0" to module-suspend-on-idle. -- Tanu
