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. ** Attachment added: "bad-sound2.m4a" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1860930/+attachment/5324432/+files/bad-sound2.m4a -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860930 Title: [Asus GX531GX] Internal speakers are sometimes noisy - bad audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1860930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
