[HowTo] set up the audio card in Samsung Galaxy Book

trying this on the samsung pen 9 15 inch (nvidia) and unfortunately it doesn’t work, it seems that “options snd slots=snd_soc_skl_hda_dsp” fails to load, so /dev/snd/ doesn’t have “hwC0D0” in it.

i was hoping theyd be similar enough, i wanna help get this working if i could!

I have the same model, but I couldn’t get it to work. What did you do with the alsa.conf file?

Do you have any suggestions for getting sound to work on Linux mint 20 (ubuntu base 20.04) on a galaxy book flex.

sof-firmware is not available through the repository.

I believe Ubuntu 20.04 uses Linux kernel v5.4 that does not support Sound Open Firmware
sof-firmware on Arch distributions was supported from kernel v5.7

Ubuntu 21.04 has package firmware-sof

Audio works perfectly fine for me on Mint 20 with kernel 5.8.0-7630-generic, following the guide

I followed your guide to the letter, untill this point. There is no such file. The computer model is an Ion 15.6. I’m not sure how to troubleshoot this. Any help would be appreciated.

Try skipping this step.

I have, still no dice. What can I do to figure out what is missing?

What kernel are you using?

5.10.2, I’ve also tried with 5.9.

I think it’s the services that are failing me.

If I do the steps manually and just run:
bash /home/YOURUSER/scripts/TO912.sh
it works! Now when I know where the problem is, I might be able to fix it myself without bothering you further. Thank you for the guide.

EDIT: I managed to fix the services by using the line below instead:
ExecStart=/bin/bash /home/YOURUSER/scripts/TO912.sh

On a slightly unrelated note, have you solved any other HW compatibility problem with these Samsung laptops? I’m thinking primarily about the ability to control the keyboard back light, or enabling the outdoor brightness mode under linux.

Hi, did you follow all the steps changing only the package manager?? I am not able to find any requested package

No, I haven’t yet. I am still looking for a way to control the keyboard back light.

Another thanks for this guide.

I recently acquired Samsung NP950XCJ for a family member and began the move from Windows to Manjaro xfce.

As previously mentioned alsa-base.conf doesn’t exist on this notebook, so I ignored section 6 above and now have sound working.

I don’t even use Manjaro, but I signed up just to say thank you. Some of the steps above seems unnecessary, but can confirm that this works on galaxybook ion with fedora 34. Thanks alot!

Hello.
I would like to thank for this help, I did it exactly as is, but I have sound on right speaker only, how can I fix it, any advice? My laptop Samsung Galaxy Flex 15.6’’, NP950QCG.

You have a different system and probably need to find the correct HDA Verbs

Connor also proved it’s effectiveness with a patch for Creative cards

Thank You for advice, I will try.

Thank you for this guide. I can confirm this works for the flex2 alpha mostly. I for some reason cannot get the headphones to work.

I make sure my headphones are plugged in. I open alsamixer from the terminal and press F6 then select sof-hda-dsp

I am able to adjust the sound level but I hear no sound out of the head phones. They are not muted in the taskbar either. I am using Cinnamon which has a different interface. I dont see an advance option for configuring audio from the icon.

Can confirm this works on the Samsung Galaxy Book Pro 360.

Made an account just to thank you for this wizardry.
