The first one need 5 OSS parametrs, the other 3 parameter. Here is my file: # ALSA portion alias char-major-116 snd # OSS/Free portion alias char-major-14 soundcore ## ALSA portion alias snd-card-0 snd-emu10k1 alias snd-card-1 snd-ens1370 alias snd-card-2 snd-usb-audio alias snd-card-3 snd-virmidi ## OSS/Free portion alias sound-slot-0 snd-card-0 alias sound-slot-1 snd-card-1 alias sound-slot-2 snd-card-2 alias sound-slot-3 snd-card-3 ## # OSS/Free portion - card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ## OSS/Free portion - card #2 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss ## alias sound-service-2-0 snd-mixer-oss alias sound-service-2-3 snd-pcm-oss alias sound-service-2-12 snd-pcm-oss ## alias sound.service-3-0 snd-mixer-oss alias sound-service-3-3 snd-pcmoss alias sound-service-3-12 snd-pcm-oss alias /dev/mixer snd-mixer-oss alias /dev/dsp snd-pcm-oss alias /dev/midi snd-seq-oss # Set this to the correct number of cards. options snd cards_limit=4 Here is my /etc/modules.d/tv . You must have in this file the options for the bttv driver, not alsa: alias char-major-81 videodev options i2c-algo-bit bit_test=1 alias char-major-81-0 off # Carte TV définie par l'utilisateur alias char-major-81-1 bttv alias char-major-81-2 off alias char-major-81-3 off options bttv card=39 latency=32 radio=1 tuner=33 The bttv cards are very cheap card and it is best to configure it to use the right parameters as to use the autoconf capability of the kernel. Those parameters are very hard to find, and if you use wrong parameters, the card will just hang and only a hard reboot will get the card running again. You will find the parameters to put in the last line here: http://www.bttv-gallery.de/ (take a long time to load).
