Finally I had to find the solution myself. Adding as the last line in file /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=alc256-asus-aio and rebooting fixed the problem. Tested with Ubuntu kernels 6.14 and 6.18.1. Please add this option to kernel/Alsa configuration to make it working after fresh installations on this Asus model without any manual changes required later. Maybe in file: path: root/sound/pci/hda/patch_realtek.c ?? (I am not kernel expert). I reported this bug as https://bugzilla.kernel.org/show_bug.cgi?id=220597 because there was no any answer from your support. But they have the following statement: "if you did not compile your own kernel from scratch, you are probably in the wrong place. Please use the following links to report a bug to your distribution instead: ..." You promise LTS support for 24.04 but there is no reaction to bug report that something WORKED when 24.04.02 was used and STOPPED WORKING with 24.04.03. The laptop is from 2021 and it has still valid support for Windows 11 and (slowly) works with this system. So, maybe there is a time to assign this bug to someone after four months? Or declare that support is valid for security patches only in case of kernel problems. ** Bug watch added: Linux Kernel Bug Tracker #220597 https://bugzilla.kernel.org/show_bug.cgi?id=220597 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2121815 Title: Internal microphone works with 6.11.0-17 kernel.
