Switching TTY breaks sound & network

Networking & sound stops when I switch to tty2. I log in with two users: user1 in tty1 and user2 in tty2. User1 starts play music via Spotify/YT. After switching to user2 after some delay music stops as well as networking (Messenger/Slack notifications).

I am using Fluxbox, NetworkManager and PuleAudio with cookie shared between users to allow share sound.

Please don't offer rewards  or bounties here, this is a volunteer driven board and no one should be expecting monetary compensation for the help they give here.

This sounds more like an issue with the distinct DBUS sessions rather than networking. What's the output of

printenv | grep DBUS

from both users.

Re: Switching TTY breaks sound & network

user1: DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus
user2: DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1004/bus

A user1 is my "main" user which I log first and run PulseAudio server

Re: Switching TTY breaks sound & network

So you definitely have distinct DBUS sessions, how exactly did you set up the sharing of the cookie? Are you running one server and others connect to that server or are maybe multiple started now?

systemctl --user status pulseaudio 
sudo fuser -v /dev/snd/*

from both?

That notifications (I'm assuming you are expecting notifications from one workspace to pop on the other?) are going to be broken can be explained by the dbus session. What's your general motivation behind this separation of users?

Yes, user1 run PulseAudio server where user2 connects to it via IP default-server = 127.0.0.1 in  ~/.config/pulse/client.conf, has empty ~/.config/pulse/default.pa and copied ~/.config/pulse/cookie from user1.

About notifications I expect to hear sound when message arrives on user1 when I am currently on user2 (tty2) and vice versa. I also noticed that Messenger or Gmail used to pop up information "Reconnecting in 30s" after I switch.
My motivation is to separate personal and work environments. It was easy to manage history of Youtube/Google searches, set different environment variables for programming to distinguish which are required to work, have clean desktop while screen sharing, easier to jump over opened windows while working, have ability to drop whole user and his data when I change job
