What we did is start from https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX534 and adjust for our machine: Create `/etc/systemd/system/audio-fix.service` with this content: ------------------------------------------------------------------------ [Unit] Description=Fix internal audio on ASUS Zenbook UX533/534 # The following options are needed to prevent the service from executing before the sound card is activated and thus failing Requires=sys-devices-pci0000:00-0000:00:1f.3-sound-card0.device # replace with the result of the previous command After=sys-devices-pci0000:00-0000:00:1f.3-sound-card0.device # same [Service] Type=oneshot ExecStart=hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf ; hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774 ; hda-verb /dev/snd/hwC0D0 0x20 0x500 0x45 ; hda-verb /dev/snd/hwC0D0 0x20 0x400 0x5289 [Install] # Make it part of the sound initialization routine WantedBy=sound.target ------------------------------------------------------------------------ Then issue this commands: ------------------------------------------------------------------------ systemctl start audio-fix systemctl enable audio-fix ------------------------------------------------------------------------ You can now reboot to check if the fix works. On our machine, sound works on speakers and audio jack output, sound is good and we could not find any trace of the bug. Thanks in advance to all kernel hackers that can propagate towards upstream a proper fix (without regression for other users). :-) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1850439 Title: No sound on ASUS UX534FT Status in linux package in Ubuntu: Confirmed Bug description: Hi, after instal Ubuntu in dual boot alongside Windows 10, I've realised there is no sound coming out of mine new ASUS Zenbook 15 UX534FT- AA024R in Ubuntu. In Windows there is no problem. Found this topic https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810214 which had the same problem with driver for Realtek ALC294 which is also mine sound card. But even with this fix it is not working on UX534FT. Can you please add fix also for this newer model?
