Try "modinfo saa7134". Due to unresolvable auto detection issues betweendifferent SECAM standards there was a secam= either DK, L or Lc optionintroduced. Anything else then 32000Hz sampling rate for TV is wrong currently andyou get that input disabled on saa7134-oss mixer. Yes, it was oncepossible, but not intended, to use 48000 also for TV/Video on saa7134chips, but gave very poor and crackling sound and is wrong. The current saa7134-alsa is simpler to use and also uses an exportedmute symbol from saa7134-tvaudio. Default distribution settings aresufficient. On recent Ubutu releases seem to be problems with an out oftree alsa there.
