I have a vivobook m7400qe and have similar problem. Audio never worked from speakers or headphones jack. Mic does work.
The solution at this link worked ONCE, then never again https://askubuntu.com/questions/1394452/sound-not-working-on-ubuntu-20-04-asus-vivobook-pro So it should be a configuration related issue. Any other solutions found over the web don't work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1903896 Title: [VivoBook Flip 14 TP410UF, Realtek ALC294, Speaker, Internal] No sound at all Status in alsa-driver package in Ubuntu: Confirmed Bug description: The sound was working just fine.
