+   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. */
