I fail to understand why pulseaudio would start capturing sound from a V4L audio at startup. I think that this is not the default for pulseaudio, though, as you're the only one complaining about that, and I never saw such behavior in the time I was using pulseaudio here. I don't know enough about pulseaudio to help on this issue, nor I'm using it currently, so I can't test anything pulsaudio-related. Lennart, Could you please help us with this issue? Thanks!
