Subject: [PATCH] FS#13996:  Have audio_hard_stop() kill the PCM output path
 entirely

We already shut down the playback path and the voice path, but that
doesn't necessarily mean the PCM hardware is idle.

Add a call to pcm_play_stop() to ensure the PCM sink is completely idle.
This will prevent a badly-timed callback from firing during a ROLO
operation.
