Hi. ## Problem, check symptoms
We have a laptop here affected by the problem. Following comment #172 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/172 > and please do not forget to also let us know what model laptop you have. * lshw says "ZenBook UX534FAC_UX533FAC" or simply "UX534FAC". * Vendor identified it as UX534FA-A8094T. > If possible please check all 4 of: > > 1. Speakers > 2. Headphones output > 3. Internal mic. > 4. Headset mic. (using a phone headset with builtin mic with a single T-R-R-S > connector) Symptoms: 1. Speakers: no sound 2. Headphones output: no sound 3. Internal mic: works 4. Headset mic (no tested) ## Check workaround: success > After testing please report back here what works (and what does not work) after issueing the 4 above commands; > hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf > hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774 Issuing the first two above allowed to get sound output. > hda-verb /dev/snd/hwC0D0 0x20 0x500 0x45 > hda-verb /dev/snd/hwC0D0 0x20 0x400 0x5289 Issuing the last two (right above) did not seem to have any effect. Full test after the four commands: 1. Speakers: "perfect" sound 2. Headphones output: "perfect" sound 3. Internal mic: works 4. Headset mic: works ## Sound quality: as good as you can get No artifacts like reported in #133. "Perfect" means as good as can be given the physical speakers (e.g. not much bass but this is normal). ## Next step: have a permanent fix Some copy-paste instructions as to how to make this fix permanent would be appreciated. Else I can figure out some and share, e.g. from https://askubuntu.com/questions/919054/how-do-i-run-a-single-command-at- startup-using-systemd ## Thanks Thanks everyone, including @j-w-r-degoede who shows that kernel developers are taking care. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850439 Title: No sound on ASUS UX534FT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
