[Kernel-packages] [Bug 1850439] Re: No sound on ASUS UX534FT
Hello again. This is a continuation of comment #185 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/185 where we describe hardware, symptoms, then #186 where we describe the permanent fix we did. ## Other problem: "nasal" sound on speakers only We noticed that some applications have normal sound (e.g. youtube in Firefox), while some others have a kind of "nasal" sound (e.g. VLC playing the same audio). I would describe the effect as similar to a very slight clipping producing high frequencies. It is relatively subtle, just as if the laptop speakers had worse quality. The problem is observed only on machine speakers, and not on analog jack output. ## Investigation We reproduced the problem using mpv. Then we tried to disable pulseaudio and have mpv play directly through alsa, which cured the problem but, well, killed all pulseaudio features. Then we instructed pulseaudio to use 48000 output sample rate, which allowed to cure the problem and allow pulseaudio. ## Local fix: force pulseaudio sample rate The fix we used is like this: In /etc/pulse/daemon.conf ensure there is a line like: default-sample-rate = 48000 Then "pulseaudio -k" to ensure no daemon with old settings exist. You might have to run "pulseaudio &" too, depending on context. Anyway, with this change the "nasal sound" problem is fixed permanently in all applications. ## Global fix Thanks a lot to people working upstream if they can provide a non- regressing global fix without users having to figure out workaround. It might be hard and we thank you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1850439 Title: No sound on ASUS UX534FT Status in linux package in Ubuntu: Confirmed Bug description: Hi, after instal Ubuntu in dual boot alongside Windows 10, I've realised there is no sound coming out of mine new ASUS Zenbook 15 UX534FT- AA024R in Ubuntu.

Following https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/185 here are instructions that provide a permanent fix. > ## 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 Hi all, This fix works on our machine, where lshw says "ZenBook UX534FAC_UX533FAC" or simply "UX534FAC". What we did is start from https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX534 and adjust for our machine: Create `/etc/systemd/system/audio-fix.service` with this content: [Unit] Description=Fix internal audio on ASUS Zenbook UX533/534 # The following options are needed to prevent the service from executing before the sound card is activated and thus failing Requires=sys-devices-pci:00-:00:1f.3-sound-card0.device # replace with the result of the previous command After=sys-devices-pci:00-:00:1f.3-sound-card0.device # same [Service] Type=oneshot ExecStart=hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf ; hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774 ; hda-verb /dev/snd/hwC0D0 0x20 0x500 0x45 ; hda-verb /dev/snd/hwC0D0 0x20 0x400 0x5289 [Install] # Make it part of the sound initialization routine WantedBy=sound.target Then issue this commands: systemctl start audio-fix systemctl enable audio-fix You can now reboot to check if the fix works. On our machine, sound works on speakers and audio jack output, sound is good and we could not find any trace of the bug. Thanks in advance to all kernel hackers that can propagate towards upstream a proper fix (without regression for other users). :-) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1850439 Title: No sound on ASUS UX534FT Status in linux package in Ubuntu: Confirmed Bug description: Hi, after instal Ubuntu in dual boot alongside Windows 10, I've realised there is no sound coming out of mine new ASUS Zenbook 15 UX534FT- AA024R in Ubuntu.

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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1850439 Title: No sound on ASUS UX534FT Status in linux package in Ubuntu: Confirmed Bug description: Hi, after instal Ubuntu in dual boot alongside Windows 10, I've realised there is no sound coming out of mine new ASUS Zenbook 15 UX534FT- AA024R in Ubuntu.
