If the problem started only a month ago then it wouldn't be pulseaudio because that hardly ever changes. Most likely it is the kernel, which gets updated more frequently.
Can you please try some older (or newer) kernel versions from here: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D and tell us if any are able to avoid the bug? ** No longer affects: alsa-driver (Ubuntu) ** Changed in: pulseaudio (Ubuntu) Status: New => Invalid ** Changed in: linux-firmware (Ubuntu) Status: New => Incomplete ** Changed in: linux-hwe (Ubuntu) Status: New => Incomplete ** Changed in: linux-hwe-edge (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1834782 Title: ASUS Zenbook UX433FN: sound stops working after a couple of seconds Status in linux-firmware package in Ubuntu: Incomplete Status in linux-hwe package in Ubuntu: Incomplete Status in linux-hwe-edge package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: Invalid Bug description: Issue: whichever sound-related action (sound +/- media keys, spotify song, youtube vid in browser,...) I do, the sound works OK for about 2-3 seconds, and then stops and becomes silent. The interesting thing is that when I stop playing the audio (ie close the browser tab with a song), after a while when I try aain the sound works again. Yet still for just the few secs. Environment: up-to-date Ubuntu 18.04, tried -hwe, hwe-edge kernels. This is a regression, the sound used to work OK on this machine, and nothing significant related to sound has changed since.
