Audio output deactivated / digital audio delayed

[nikgnomic]

“PCM 2.0” disappears a few seconds after I paused the playback

how to turn off that interruption? Where does it come from?

The interruption might be due to PulseAudio module module-suspend-on-idle
that module will suspend an audio sink after a few seconds of inactivity to save power

The PulseAudio module can be unloaded temporarily with this command

pacmd load-module module-suspend-on-idle

@nikgnomic

if that works Pulseaudio configuration can be changed to disable the module permanently

sudo sed -i 's/load-module module-suspend-on-idle/#load-module module-suspend-on-idle/g' /etc/pulse/default.pa

this adds a comment tag ‘#’ at the start of the line to stop module being loaded
