Hey I think I have the same bug as you. Does it feels like random tv static noise is playing on your speaker randomly, and the test left and right not play anything?

Description: Ubuntu 24.04.1 LTS Release: 24.04 2) Not sure about which package is affected so not providing apt-cache policy. 3) What you expected to happen * Machine makes no electronically generated sound when active, in a suspended state (or, obviously, off). * Machine plays desired sound through integrated speakers, unless a cable is plugged in the jack or another output (e.g. Bluetooth) is selected. 4) What happened instead The machine has sound issues every day, more often than not. Most of the problems are not about impossibility of playing desired sound, rather the existence of undesired sound when no sound is being played. Most of the information below was recently checked though some details are from older memories and might not be exact. Specific things can be tested again on demand to ascertain them (some need to wait for an occurrence to come up). All noise reported below is not fan noise. Actually the machine has no fan. The noise is electronically generated hiss and what we would call "digital splutter". We have one recording that we can provide and more can be made if useful. * (observed in the last hour) Click sounds now and then. Most of the time (not at all times, though) a high pitch continuous hiss sound with digital splutter is heard. The noisy hiss is not very loud but sufficient to be annoying in a moderately quiet place. * (observed in the last hour) When suspending the laptop, there is a 5 second gap between the time the screen dims and the time the power LED changes. During this time, the hiss is different. Then, while the machine is suspended the power LED brightness modulates with period around 4 seconds and the hiss sound also: it is different depending on the current brightness of the LED. * When playing sound successfully through the integrated speakers, clicks and hiss are momentarily not heard. Playing digital silence suffices to momentarily suppress clicks and hiss. * Sometimes no desired sound can be played and pavucontrol reports only "dummy output" and no click or hiss is heard. * Bluetooth earphones can be set up and used. The sound heard through them has no click or hiss. * The laptop has an audio output jack. When playing sound through it to an external audio system, the desired sound is also heard through the laptop speakers at the same time. * When suspended, the battery drains in about two days. It sounds reasonable that sounds heard are correlated to something that consumes power when suspended. Thank you for your attention. We are willing to do any reasonable experiment or workaround to be tried.
