Discord Screen Share Fix Audio on Linux

No need too much bla-bla lets just get it over with.

Requirements

• pulseaudio: This thing is our savior. Usually comes pre-installed. If not then probably your system is using something else so better not use this script than breaking your system by replacing your current one with pulseaudio, this script is for pulseaudio only.
• pavucontrol-qt: To configure input and output from mic and app into discord. Very useful tool for routing your audio.

Setting Up

Just run the script:

./discord-scrshrwa.sh

chmod +x it first if it's not executable yet.

And then boot up discord, hop in a VC and start streaming. It's that ez, so simple right.

hol' up, it's not done yet

Now you're in a vc and streaming some hanime with no audio, your friends and gfs that are watching are complainin in the background as you're doing these:

Open pavucontrol-qt and find your browser/game in Playback tab and set its playback on app, and then go to the Recording tab and find something like WEBRTC VoiceEngine :recStream and set its source to Monitor of mic+app.

Anddddddd Done

Close (or don't) pavucontrol-qt.

Go back to discord, unmute yourself and continue your hanime and watch together with everyone, safe and sound.

Tips

• You can mute your mic in pavucontrol-qt.
• Try setting discord input sensitivity to -100dB(or -99dB if you want the indicator to show when your audio is inactive) on discord settings.
• If you wanna remove the virtual streams, run

pactl unload-module <number>

where <number> is one of the script's terminal output. Do it once for each number. If you forget the numbers, run

pactl list

and find the virtual streams number.

• If discord ever prompt you to switch audio device, don't switch!
• If you don't want to run the script every time you boot up your PC, copy the codes from the script (exclude the first line) and append it to your /etc/pulse/default.pa, make sure to remove the pactl prefix from each line.
• There's pavucontrol which uses GTK, if you have display issue with pavucontrol-qt you might want to use that.

Issues

• If discord crashes when streaming, ignore it. Try streaming again, usually only one time crash.
