27 | /* ENABLE_PVR150_WORKAROUND activates a workaround for a hardware bug that is |
| 28 | present in Hauppauge PVR-150 (and possibly PVR-500) cards that have | |
| 29 | certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The | |
| f95006f8 HV |
30 | audio autodetect fails on some channels for these models and the workaround |
| 31 | is to select the audio standard explicitly. Many thanks to Hauppauge for | |
| 32 | providing this information. */ | |
