The pattern is... you edit the default configurations of system daemons until they don't work, then complain on the internet? Wow! it's terrible that your init system has been fighting you! Let's figure out what custom unit you wrote which is causing the problem. Unless your alsa devices are broken, I find it unlikely that pulseaudio 10 will do anything untoward; if it does, well then, time to fix a bug, good thing there are so many people working on pulseaudio. Avahi... well idunno. Avahi tends to be true to the name of ZeroConf networking. I have never written an avahi configuration in my life, and yet it works for me. Maybe you have a malicious mDNS peer on your network? I'm sorry you have to experience that! If you could fire up wireshark and pass the hail mary instead of letting it drop to the green, that would be great.
