+/* The CARDTYPE_PVR150_WORKAROUND cardtype activates a workaround for a
+   hardware bug that is present in PVR150 (and possible PVR500) cards that
+   have certain NTSC tuners (tveeprom 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. */
