Hello:
I use pulseaudio's parec to record an audio stream played
in a browser. I use openSUSE 15.1 with its default pulseaudio
version pulseaudio-11.1-lp151.5.3.
This is what I do:
load null sink:
pactl load-module module-null-sink sink_name=stream
I move the firefox browser sound to null output in pavucontrol GUI.
I record the stream with parec:
parec -d stream.monitor --file-format out.wav
This works well. But I also want to switch between two user's
desktop.
User1 is on VT7, user2 is on VT8.
I start to record on VT8, then I switch to VT7; the record is OK.
But when I switch back to VT8, the record gets a short interrupt
(pause), which is annoying. An image of the waveform showing the
short pause in the can be seen here:

How could I fix this, to get an uninterrupted recording?
Are these actually different system (unix) users? With different
UIDs?
If so, pulse doesn't really work in a multi-user environment by
default.
How have you configured pulse to use multiple users? That may shed
some
light on what's causing your cut-outs.

Thank you.
These are two different users with different UIDs.
They work alternately in the system. User2 records the stream in his
session
in VT8 X11 terminal. After starting to record user1 switches to his VT7
X11 session. Occasionally user2 switches bacj to his session. During
the
record they switch sessions several times.
I haven't configured pulseaudio, just use the default openSUSE setup.
Earlier I tried system-wide pulseaudio to be able to listen to the
stream
in both sessions. It worked, but pacmd doesn't work in system wide
mode,
therefore I removed it (the pulseaudio system wide package).
Thanks,
