Comment 22 for bug 2050040

even when removing sudo apt remove --purge alsa-base pulseaudio and sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

and rebooting and not sound settings now in settings sound nothing. The sound is still beeping off and on no flickering on the dock anymore and in settings sound, but the sound is still beeping off and on. I hope that helps with some info on this.
