pulseaudio log
After launching an app that needs microphone, like for example Discord or
Telegram-Desktop, system sound starts to crackle and echoing. Then, if I start
randomly changing system volume up/down for some seconds, the audio will fix
itself. I first thought it was a Discord only problem, but it will happen with
every application accessing microphone.
I have tried following these steps without success:
<a href="https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling">https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling</a>
Here are some reports from the discord subreddit, people having similar
problems:
<a href="https://www.reddit.com/r/discordapp/comments/7kuki9/microphone_crackling_only_on_discord_linux/">https://www.reddit.com/r/discordapp/comments/7kuki9/microphone_crackling_only_on_discord_linux/</a>
<a href="https://www.reddit.com/r/discordapp/comments/7si7s3/linux_crackling_sound_in_application/">https://www.reddit.com/r/discordapp/comments/7si7s3/linux_crackling_sound_in_application/</a>
but since everyone either fixed the problem in a different way or didn't
succeed (like me), I supposed it was a pulseaudio problem. I attached
pulseaudio log while launching discord and experiencing the problem.
OS: Archlinux
Linux Version: every version since mid 2017 (when I installed arch)
Pulseaudio version: every version since mid 2017</pre>
