No sound from speakers on ASUS Zenbook UX3402ZA_Q409ZA

Question

I installed Ubuntu 23.04 on my ASUS Zenbook UX3402ZA_Q409ZA. I am able to hear sound when the headphones are connected however the internal speakers do not output sound when nothing is connected to the headphone jack. I have tried reloading alsa and installing pulse audio to change the levels but to no success. Any help would be appreciated! Thank You! -Aubury-

Answer 2

I had the same problem on Ubuntu 22.04 with Zenbook UX5400Z. My computer is set up to have dual boot with Windows. I found a recomendation here to disable fast boot in windows (control panel -> power options -> Choose what the power buttons do -> Change settings that are currently unavailable -> Under 'Shutdown settings,' uncheck the 'Turn on fast startup' box) This immediatly fixed the issue.

Sometimes it can be that the correct channel is muted or its levels are set so low that no sound can be detected. How you can check if that's the case, is if you open alsamixer in the terminal, and you should see something like this.

I had given up to fix the issue with my Asus Zenbook UX3402ZA by using external speakers all the time. Today, upon upgrade to Ubuntu 24.04, the problem is solved and I can get sound from internal speakers.
