The problem still occurs on the latest stable PulseAudio packages (1:15.0+dfsg1-1ubuntu2.2) for Ubuntu 21.10. Also, doing a "pulseaudio -k" on the Terminal, and then restarting any software that was outputting audio, fixes the issue. I've noticed that this only happens after the output audio device is changed between the available devices. So, going from the "HDMI/DP3 output" to "Digital Output" and then back will cause the crackling after a few minutes.

The amount and volume of the static will depend on the sound/music that is being played, and this only starts occurring after a somewhat long time (30 minutes or more). What is interesting to see is that while playing back music from Spotify (Snap) the static will only start after a second or so, but when playing YouTube videos on Firefox, it will be immediate and output that static while the video is playing. I've added two sound recordings, one while playing back a song from Spotify and the other while playing a song from YouTube. This issue goes away when restarting the PulseAudio service, but it comes back after a random amount of time. 1) Description: Ubuntu 21.04 Release: 21.04 2) pulseaudio: Installed: 1:14.2-1ubuntu1 Candidate: 1:14.2-1ubuntu1 Version table: 1:14.2-1ubuntu1.1 1 (phased 10%) 500 http://br.archive.ubuntu.com/ubuntu hirsute-updates/main amd64 Packages *** 1:14.2-1ubuntu1 500 500 http://br.archive.ubuntu.com/ubuntu hirsute/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: pulseaudio 1:14.2-1ubuntu1 ProcVersionSignature: Ubuntu 5.11.0-18.19-generic 5.11.17 Uname: Linux 5.11.0-18-generic x86_64 ApportVersion: 2.20.11-0ubuntu65.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: matheus 18662 F.... pulseaudio /dev/snd/controlC2: matheus 18662 F.... pulseaudio /dev/snd/controlC0: matheus 18662 F.... pulseaudio /dev/snd/pcmC0D8p: matheus 18662 F...m pulseaudio CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Mon Jun 14 16:58:43 2021 ExecutablePath: /usr/bin/pulseaudio InstallationDate: Installed on 2021-05-03 (41 days ago) InstallationMedia: Ubuntu 21.04 "Hirsute Hippo" - Release amd64 (20210420) ProcEnviron: LANG=pt_BR.UTF-8 LANGUAGE=pt_BR:pt:en PATH=(custom, user) SHELL=/bin/bash XDG_RUNTIME_DIR=<set> SourcePackage: pulseaudio UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/11/2021 dmi.bios.release: 5.17 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 3002 dmi.board.asset.tag: Default string dmi.board.name: PRIME B450-PLUS dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: Rev X.0x dmi.chassis.asset.tag: Default string dmi.chassis.type: 3 dmi.chassis.vendor: Default string dmi.chassis.version: Default string dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr3002:bd03/11/2021:br5.17:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnPRIMEB450-PLUS:rvrRevX.0x:cvnDefaultstring:ct3:cvrDefaultstring: dmi.product.family: To be filled by O.E.M. dmi.product.name: System Product Name dmi.product.sku: SKU dmi.product.version: System Version dmi.sys.vendor: System manufacturer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1931902/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
