The most important insmod option for bttv is "card=n" -to select the correct card type. If you get video but no sound you've -very likely specified the wrong (or no) card type. A list of supported -cards is in CARDLIST.bttv - -If bttv takes very long to load (happens sometimes with the cheap -cards which have no tuner), try adding this to your modules.conf: - options i2c-algo-bit bit_test=1 - -/*(DEBLOBBED)*/ - -If your card isn't listed in CARDLIST.bttv or if you have trouble making -audio work, you should read the Sound-FAQ. - - -Autodetecting cards -------------------- - -bttv uses the PCI Subsystem ID to autodetect the card type. lspci lists -the Subsystem ID in the second line, looks like this: - -00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02) - Subsystem: Hauppauge computer works Inc. WinTV/GO - Flags: bus master, medium devsel, latency 32, IRQ 5 - Memory at e2000000 (32-bit, prefetchable) [size=4K] - -only bt878-based cards can have a subsystem ID (which does not mean -that every card really has one). bt848 cards can't have a Subsystem -ID and therefore can't be autodetected. There is a list with the ID's -in bttv-cards.c (in case you are intrested or want to mail patches -with updates). - - -Still doesn't work? -------------------- - -I do NOT have a lab with 30+ different grabber boards and a -PAL/NTSC/SECAM test signal generator at home, so I often can't -reproduce your problems. This makes debugging very difficult for me. -If you have some knowledge and spare time, please try to fix this -yourself (patches very welcome of course...) You know: The linux -slogan is "Do it yourself". - -There is a mailing list: linux-media@vger.kernel.org -http://vger.kernel.org/vger-lists.html#linux-media - -If you have trouble with some specific TV card, try to ask there -instead of mailing me directly. The chance that someone with the -same card listens there is much higher... - -For problems with sound: There are a lot of different systems used -for TV sound all over the world. And there are also different chips -which decode the audio signal. Reports about sound problems ("stereo -does'nt work") are pretty useless unless you include some details -about your hardware and the TV sound scheme used in your country (or -at least the country you are living in). - - -Finally: If you mail some patches for bttv around the world (to -linux-kernel/Alan/Linus/...), please Cc: me. - - -Have fun with bttv, - - Gerd - --- -Gerd Knorr <kraxel@bytesex.org> |
