Re: [LAU] Ubuntu Studio 14.04 Pulse removal question

Ok so even opening QasMixer will currently get PA to spawn when it wasn't previously running. I see Pulse is listed under Mixer Devices, plus it also appears very likely that is the mixer currently set as my Default from looking at the layout.

Is there some configuration to Alsa I should do to prevent this when not using PA?

I just had a thought as to the cause of this. I think I might have still had my Volume widget in my Panel showing the control from PA at that point and since changed it to display amixer's. From what you say this likely would have caused PA to start, even though I had disabled it in Autostart.

Hope you forgive me for not confirming this was the cause right now :)

Doesn't seem to be respawning now, definitely was still loading at startup before I added the pulseaudio -k command to jack options but my laptop has been running all night, so up for maybe 16 hours since last reboot and this is my output from trying to kill pulseaudio in terminal.

$ pulseaudio -k
E: [pulseaudio] main.c: Failed to kill daemon: No such process

Clearly not respawned itself in all that time. But the fact it will do if any program requests it is quite a good hint for me, and hopefully I will see a change if it pops up again when I try and use something.

Once I'm totally sure nothing is trying to access pulse any more I might add this line. Is there any difference between adding it to rc.local and adding it as an Autostart option, like I did with qjackctl?

And then this when even more confident ;)

Yeah I worried and thought I had heard there could be problems with removing. So I aim to fully ensure it's never running and I can be happy with that :)
