Public bug reported: There is a bug that occurs between PulseAudio and Wifi drivers. I posted this Issue on PulseAudios Git. Where after a long investigation it looks like it's a problem with Wi-Fi drivers in PopOS. The problem occurs when Wifi is Turned On, but not connected. If you (in this state) play any audio from any source it stutters and lags (sample audio clip appended). Looks like this issue is known and I found it on some other forums. I was told by PulseAudio Maintainers to notify distro devs about that issue. Here is the issue link:

In the linked Issue you can find all needed logs and audio samples of stuttering and lags My 'lsb_release -rd: ```text $ lsb_release -rd Description: Pop!_OS 20.10 Release: 20.10 ``` Version of my package: ```text $ sudo apt-cache policy backport-iwlwifi-dkms backport-iwlwifi-dkms: Installed: (none) Candidate: 8613-0ubuntu1 Version table: 8613-0ubuntu1 500 500 http://es-mirrors.evowise.com/ubuntu groovy/universe amd64 Packages 500 http://es-mirrors.evowise.com/ubuntu groovy/universe i386 Packages 500 http://us.archive.ubuntu.com/ubuntu groovy/universe amd64 Packages 500 http://us.archive.ubuntu.com/ubuntu groovy/universe i386 Packages ``` Here is my inxi: ```text $ inxi -Fxxx System: Host: pop-os Kernel: 5.8.0-7630-generic x86_64 bits: 64 compiler: gcc v: 10.2.0 Desktop: N/A wm: gnome-shell dm: GDM3 3.38.1 Distro: Pop!_OS 20.10 base: Ubuntu 20.10 Groovy Machine: Type: Desktop Mobo: ASRock model: H110M-DVS R3.0 serial: <superuser/root required> UEFI [Legacy]: American Megatrends v: P1.20 date: 04/17/2017 CPU: Info: Quad Core model: Intel Core i5-7400 bits: 64 type: MCP arch: Kaby Lake rev: 9 L2 cache: 6144 KiB flags: avx avx2 lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx bogomips: 24000 Speed: 3376 MHz min/max: 800/3500 MHz Core speeds (MHz): 1: 3382 2: 3320 3: 3383 4: 3338 Use of uninitialized value $working[3] in substitution (s///) at /usr/bin/inxi line 21120.
