 When trying to play a mono PCM audio track from a DVD, I hear nothing and
 see lots of audio decoding errors in the traces.
 The problem appears to be hardware-related (or configuration) as the same
 DVD plays ok in a virtual machine on a different physical machine.

 Myth is set to use 'ALSA:default'.  pulseaudio is running.  aplay -l
 produces:
 **** List of PLAYBACK Hardware Devices ****
 card 0: PCH [HDA Intel PCH], device 0: ALC889 Analog [ALC889 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
 card 0: PCH [HDA Intel PCH], device 1: ALC889 Digital [ALC889 Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

 Analogue audio output is being used.

 The DVD is available in stuartm's DVD repository
 (LangSPU_MultiFormat.iso).  The French audio track is stored as mono PCM
 (due to #11376, select 'E/F/D' from the menu and then change to French).
