/* ENABLE_PVR150_WORKAROUND activates a workaround for a hardware bug that is
   present in Hauppauge PVR-150 (and possibly PVR-500) cards that have
   certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The
   audio autodetect fails on some channels for these models and the workaround
   is to select the audio standard explicitly. Many thanks to Hauppauge for
   providing this information. */
