Non riesco ad usare la scheda di acquisizione

[fbcyborg]

Salve a tutti,

è qualche anno che vorrei far funzionare la mia scheda di acquisizione ed ancora non ho capito come fare.
La mia scheda è una Kworld DVB-S 100, che oltre a fare da scheda satellitare fa da scheda di acquisizione analogica. L'ho già usata in passato su un PC con Windows per entrambi gli scopi e non ho avuto problemi. Qui su Linux riesco a farla andare solo come scheda satellitare, ma di acquisizione non se ne parla.
Sicuramente non so nemmeno quale software sia opportuno (sono su KDE), però non capisco se viene rilevata o no. Eppure i driver del kernel credo siano compilati tutti.

Ecco l'output di lspci:
05:00.0 Multimedia video controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
05:00.2 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)

Qualcuno mi sa dare una mano per capire come usarla come scheda di acquisizione?

Grazie, solo che non mi funziona né con la webcam né con l'ingresso analogico.

Mi daresti qualche idea per fare delle prove più "sicure"?

Inoltre dmesg dice:
cx88[0]/0: unknown tv audio mode [0]
cx88[0]/0: unknown tv audio mode [0]

prova a guardare se qui c'e la tua scheda

provala senza la webcam

cosa ti da
dmesg | grep cx88
ls /dev/video*

xdtv_wizard
xdtv -c /dev/video0
xdtv -c /dev/video1

puoi provarla anche con xawtv

Sembrerebbe non esserci, è una KWorld DVB-S 100. So che non è una marca eccellente e che è principalmente una scheda satellitare, ma su winsozz funziona bene anche come acquisizione.
