Sound glitch on certain app and system sounds

I've been experiencing an annoying sound glitch since my latest update (update of 23/02/2022 of Ubuntu 20.04.4 LTS). Its a periodic buzz which happens when sound is coming out of my headset. The effect is present for system sounds like alert sounds or backspace, for music coming from Spotify and when I'm in a call in Teams-for-linux. Interestingly, the effect is not present on youtube. I can listen to music on youtube (firefox)without any glitch at all but that's about the only place. Here's a copy of the output of sudo lshw -c multimedia:

I have a corsair hs45 headset which is connected via usb (the audio jack is in a usb dongle) which has been working flawlessly for over a year and was plug and play with ubuntu originally. Any one has that issue or any idea how to fix it? Thx

I have it fixed when I restart the pulseaudio, but before the system restarts.

It looks like this bug:

Change Pulse Audio's default sample rate to 48000.

sudo nano /etc/pulse/daemon.conf

Find the lines starting with

; default-sample-rate
; alternate-sample-rate

Remove the ; and change the values to 48000 so it looks like this:

default-sample-rate = 48000
alternate-sample-rate = 48000

Save the file Then restart PulseAudio:

systemctl restart --user pulseaudio

If that doesn't work then just kill it and it will restart:

pulseaudio --kill
