Same here, I have a Lenovo X13 Gen1 notebook with an AMD 4750U Ryzen processor. The integrated sound chip works without problem, but when using the sound card in the Lenovo USB dock, the problem appears. Rebooted several times but the problem persists. Downgrading to the 5.13.0-35 kernel removes the problem.

After rebooting into linux-image-5.13.0-35-generic, the noises were gone. Some details that I've noticed: 1. When launching pulseaudio manually, not as a daemon, the problem disappears. 2. If I set the log-level in /etc/pulse/daemon.conf to debug and reload it, the log has a lot of: Mar 23 17:22:44 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA! Mar 23 17:22:43 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA! Mar 23 17:22:39 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA! Mar 23 17:22:38 ainar-ThinkPad-X13-Gen-1 pulseaudio[76435]: Wakeup from ALSA! Which roughly correspond with the noises. 3. The usual "rm -f -r ~/.config/pulse && pulseaudio -k && sudo alsa force-reload" doesn't seem to help. Only a kernel downgrade does. 4. This happens both in Firefox (where I first noticed it) as well as in Totem and in system sounds. 5. I tried to report the bug using "ubuntu-bug audio", but it showed me six inputs of which three looked the same, and for each of them it told me that it pulseaudio wasn't configured to use it. I'm ready to collect logs and other info within the next days.
