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: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling

Here are some reports from the discord subreddit, people having similar problems:

https://www.reddit.com/r/discordapp/comments/7kuki9/microphone_crackling_only_on_discord_linux/
https://www.reddit.com/r/discordapp/comments/7si7s3/linux_crackling_sound_in_application/

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

Based on that I get the impression that you don't have these problems any more, so I'll close this bug. Thanks for reporting!
