Hello Hans,
Please find my report below. Let me know if you need any additional information.
And thank you.

The good news is that I found an article that MAY help to reverse
engineer HDA verbs and other commands needed to configure our sound card
properly: https://jcs.org/2018/11/12/vfio. Basically, we need to pass
HDA Audio PCI-E device to the Windows VM and analyze all the traffic.
Not easy but it's so
Ha. And just noticed the comment Kai-Heng Feng wrote before

This crazy script contains all SET and unknown commands sent from the

On the negative side: the sound has strange artifacts on speakers. And
headphones are not working properly once inserted.
If you want to experiment yourself - please use previous traces and the
following Python scripts:

Here is the behaviour on my UX534FTC:
1. Power cycle.
2. Execute two commands from the Erikas' comment.
3. Start youtube video with sound.
Actual result: No sound from speakers.

The strange thing is that built-in microphones ARE actually working on
my notebook out of the box. At the least sound meter IS moving for
internal microphones in the settings. And I also found out another bug

For me just usual reboot is enough. I reboot the notebook, start some
application that plays sound and then execute the commands below. And
everything works as a charm on my UX534FTC.
About reset - try also "alsa force-reload" and maybe the following
command:

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

Please create a separate issue for UX582ZM. For UX534 the Realtek team
pushed their own changes, regardless of what we recovered from the dump.
Maybe the Realtek and Ubuntu teams will help again if the UX582ZM issue
