Not sure if this is the same but in cases where no sound device is detected/recognized and Pulseaudio(which has a dummy output) is not being used I've seen the applet's icon not appear

This happens here if i restart session. The pulseaudio daemon restarts automatic if killed.
Means the daemon is running if the session is closed.
Starting a new session starts the pulseaudio daemon again via auto start, in result i've often several pulseaudio daemons running. The applet doesn't like this.
Killing all pulseaudio daemons with 'killall pulseaudio' brings the applet back for me.
Not sure if this is your issue........

See pulseaudio default config /etc/pulse/client.conf
; autospawn = yes

Found this issue and want to add that sound icon sometimes crashed and here is .xsession-errors log:

I have seen this from time to time as well.
Usually when adding/removing USB audio and then opening vol control

[lukefromdc]

I have never had the volume applet disappear, but on occasion the network-manager-applet will disappear(by not showing up as the session starts-always at session start). Good chance it's the same or a similar issue-and I've seen it both with nm-applet as a tray icon AND as an indicator. Not all that often but not unheard of either

We've been waiting for a fix since 2018 to avoid this crash and have the most perfect desktop possible.
