No sound on LG Gram 17 inch from 2023 (model: 17Z90R) #4363

Open tchwpkgorg opened 1 year ago

tchwpkgorg commented 1 year ago

I have an LG Gram laptop released in 2023 (with 13th Gen Intel(R) Core(TM) i7-1360P CPU). Audio over bluetooth works, but unfortunately does not over laptop's speakers.

Tried with kernels 6.2.x, 6.3.x and 6.4-rc2 and with firmware-sof-signed 2.2.5 on Ubuntu 23.04.

alsa-info output: http://alsa-project.org/db/?f=101eaeda80f5c897d0e8679608fe4b476e536f52

We really need to know if this is an amplifier-only issue, and whether it happens also with the snd-hda-intel driver. Bluetooth is usually irrelevant as not handled by the audio subsystem except in ADL+ Chrome devices.

See https://thesofproject.github.io/latest/getting_started/intel_debug/suggestions.html for some pointers to refine the issue

alsa-info with kernel 6.3.3 and firmware-sof-signed 2.2.5 on Ubuntu 23.04:

http://alsa-project.org/db/?f=e0983a6a3ca0a6cefed9bab2f2bb25c3b61bc653

Added, rebooted - didn't help.

I did boot the laptop with Windows first. After booting into Ubuntu 23.04, there was no audio.

I'm afraid I'm not able to do it.

Also something too complicated for me to diagnose.

$ aplay -l

Playback device is hw:0,0

I see Ubuntu's mixer indicator going up and down when playing music. Just no actual sound getting from the speakers.

If there is anything I can try, please let me know!

Also - not sure if it has any meaning - there is audio when I use a headphone jack and headphones. Just no audio with laptop's speakers.

plbossart commented 1 year ago

Thanks @tchwpkgorg so the conclusion is that your amplifier configuration is not well handled in the Linux HDaudio case, be it with the legacy snd-hda-intel or the SOF driver.

I am afraid I don't have a turn-key solution, the "reverse-engineer windows" is the only way to progress. It's problematic indeed because it requires a rather elaborate set of skills - I have never done this myself.

In the short-term, USB speakers seem the only work-around.

tchwpkgorg commented 1 year ago

And is it expected that I see several sof-hda-dsp devices?

(none of them play audio)

plbossart commented 1 year ago

The 'pro' stuff is an invention from PipeWire IIRC. I have no idea what this is. There is only one driver and a set of PCM devices exposed by this driver.

Open a terminal and type: "aplay -l" and "arecord -l" and you'll see what the card supports.

OK, this is sad.

So in the end - assuming someone fixes it properly one beautiful day - where would be the fix coming from? A kernel update? sof-firmware? Some other package?

plbossart commented 1 year ago

kernel update on a windy day.

tchwpkgorg commented 1 year ago

Is "hda-verb" an option here?

I see some people were able to fix their audio on Linux using hda-verb, i.e.: https://www.linux.org/threads/solved-asus-zenbook-15-ux534f-realtek-hd-audio-problem.27384/

Just unsure how they came up with rather cryptic commands like:

hda-verb /dev/snd/hwC0D0 0x20 0x500 0x1b
plbossart commented 1 year ago

by reverse-engineering the Windows driver, see https://thesofproject.github.io/latest/getting_started/intel_debug/suggestions.html#reverse-engineer-the-windows-audio-driver

apolychrome commented 1 year ago

They mention here that this issue was fixed in sof-bin 2.2.6 https://github.com/clearlinux/distribution/issues/2923

You need the right hda-verbs. Solutions is here:

Thanks. this worked，my lg gram 17 have sound now。 but the left channel and right channel does not have same volume

damien-bafile commented 5 months ago

This fix works but volume is crazy loud and uneven left vs right. Really hope one day it gets fixed properly

carlos5577 commented 5 months ago

I'm just going to add the correct order of steps to fix this issue since I wasnt a linux expert guru was able to solve this with the following links and gude on mint

First thing first. You need to install the alsa tools which is not very clear, otherwise that script mention here will fail

sudo apt install alsa-tools

then download the sh and make it executable and save https://github.com/joshuagrisham/galaxy-book2-pro-linux/blob/main/sound/necessary-verbs.sh

First, grab the file "necessary-verbs.sh" from here. Then, mark the file executable: Code:

chmod +x necessary-verbs.sh

I moved the file to /usr/local/sbin

Then create a systemd unit file to run at startup in /etc/systemd/system. This causes the script to run at each startup (actually, it doesn't need to be run again after a warm reboot, but I don't know how to specify that in a unit file.)

This File will look like this and have this name under /etc/systemd/system necessary-verbs.service

You can start this file like this at startup after you made the necessary executable permissions systemctl daemon-reload systemctl enable necessary-verbs.service
