Disabling pipewire whitenoise on idle

Update from 2024-03-25
Wireplumber changed and nothing I wrote here works anymore, but one thing still... wireplumber is horrible to configure.

I’m writing this here so I “don’t forget”.

My speakers emit a annoying whitenoise when they are turned on but there’s no signal, the problem is that my ArchLinux setup is putting the sound board into idle mode to save power after 3 (or 5?) seconds, so every time I stop listeing something, after 3 (or 5?) seconds the whitenoise starts… really annoying.

I fixed this once, but I was lazy enough to edit system files instead of user files, so today I updated wireplumber again and the whitenoise was back there.

To let you and future me repeat the same mistake of present mine, if this happen to you, edit these files:

Comment this line from /usr/share/wireplumber/main.lua.d/90-enable-all.lua:

-- Automatically suspends idle nodes after 3 seconds

Restart wireplumber:

systemctl --user restart wireplumber

Months ago I had also to edit /usr/share/wireplumber/main.lua.d/50-alsa-config.lua

Uncomment this line at end and set the value to 0 as the comment says.

--["session.suspend-timeout-seconds"] = 0,  -- 0 disables suspend

But nowadays the 90-enable-all.lua seems enough.
