Bug Description

I have an Asus Zephyrus S GX531GX laptop and a pair of Asus Delta USB headphones. When the headphones are plugged in during boot the internal speakers won't work. There is only crackling sound coming from them. It doesn't help in I unplug the headphones. There is no problem if they are not plugged in during boot. I'm using Ubuntu 19.10.

Please let me know if you need more information.

I was wrong about the headphones. They were not plugged in at all this time and the sound of the internal speakers are messed up. I'm attaching a sound recording I just made. If I switch to my monitors' speakers they work fine.

Can you please try the latest kernel and tell us if that improves the situation?

I've installed the kernel packages following the guide (sudo dpkg -i FILENAME.deb) but I got the "You need to load the kernel first" grub error message.

I guess some steps are missing from the guide?

I couldn't load kernel 5.5 because secure boot was turned on. My bad, sorry.

I was able to test the sound with kernel 5.5 after disable secure boot but there is no improvement. The audio is still bad. I'm attaching another file. It sounds like it's a cassette player running out of battery.

I haven't had this problem for some time now. Maybe there was an update that fixed it?

However sometimes the sound volume controller in the top right corner is no associated with sound device being used. I mean when I change the volume or mute it nothing happens because it controls some other device not the one being used.

The distorted audio problem just came back. I think it has something to do with this system being dual boot (Windows 10 and Ubuntu 20.04). When I only use Ubuntu there is no problem. As soon as I stop using Windows and reboot to Ubuntu the noise comes back.
It's almost like a turntable loses power and the playback slows down and stops.

This audio problem seem to be only happening when I reboot from Windows to Ubuntu. To fix it I have turn off the computer and turn it on again. Rebooting doesn't fix it.
If I turn it off after using Windows and cold start it to boot to Ubuntu there is no problem.
