I've loaded bttv.o as a module, and videodev is built into the kernel. This is turn loads tuner.o. The picture and sound come up fine. The problem is, the sound never goes off!! As soon as I modprobe the bttv module (and tuner.o is automatically inserted), the sound comes on, even before I start up any TV viewing program. This is with kernel 2.4.18 using Alsa 0.5.12 with OSS emulation on a SB 128PCI card. I don't think that alsa has anything to do with it. I tried this in XawTV. It seems like there is no control over the sound output at all. When I press mute in XawTV, the sound still stays on. The only way to kill the sound is to 'modprobe -r' the bttv module. I've connected the audio cable from the output of the TV Wonder card to the line-in of the sound card. Any suggestions !!! Thanks, Steve
