If you want, feel free to propose a patch fixing that logic at saa7134, instead of just removing it.
Hi, I've just verified that pulseaudio indeed does the sound capturing on startup:

If pulseaudio is starting sound capture at startup, then it is either a pulseaudio miss-configuration or a bug there. 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! Mauro
So your proposal is not going to fix anything at all.
Can we get back to discussing/applying mine then? And if the other drivers has that autounmute logic, then I suggest removing it there as well. You have not named any use-case for it, so I think there is none. I also think that the whole auto-unmute logic in your drivers is entirely flawed: for instance, I don't think recording from the sound card will automatically unmute its line-in or something else, so you are probably not following the generic alsa style here. I am adding alsa-devel to CC to find out what they think about that whole auto-unmute question.
