Eugene, Looks like your device has a different audio hardware (??!!) and even a separate bass speaker. If, of course, it's not just ALSA behaving different on Arch and Ubuntu with different kernel versions. Here is my alsa-info output for comparison: http://alsa- project.org/db/?f=de23539e56920af428008882c75fdb912728f30e. There is no bass speaker on my machine. And also you have other hda connections, driver pin configs and some other stuff. Unfortunately the only thing I can recommend you is to follow my approach described in comments #131 and #128 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/131 and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/128). Basically you need to: 1) install Windows 10 in the Qemu virtual machine: https://wiki.gentoo.org/wiki/QEMU/Windows_guest 2) list you IOMMU groups, add all devices from IOMMU group to the vfio driver: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Enabling_IOMMU Here is the example for my machine and my devices, replace the corresponding string in /etc/default/grub with your devices: GRUB_CMDLINE_LINUX_DEFAULT="text vfio- pci.ids=8086:02a3,8086:02c8,8086:0284,8086:7270 iommu=pt intel_iommu=on" 4) upgrade-grub 5) reboot 6) start windows virtual machine with the audio card forwarded, example: https://gist.github.com/s-kostyuk/b8940413cc4334092a6fcc58661e0278 7) install the Realtek driver from here: https://www.asus.com/us/Laptops/ASUS-ZenBook-15-UX534FTC/HelpDesk_Download/ IMPORTANT: Search for appropriate drivers for YOUR notebook if it's not UX534FTC. 8) in device manager - manually change the driver for your audio device to the "Realtek High Definition Audio Version 6.0.8794.1" (or similar) 9) ensure that everything is working in windows (mic, speakers, headphones, etc) 10) disable the device in device manager 11) stop windows VM 12) attach Ubuntu 20.04 Live CD (or other) with the audio still forwarded 13) ensure that the sound is working in VM 14) enable dump_coef, run alsa-info.sh and try to find the differences with vanilla state -- 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?
