[alsa-devel] no sound in laptop ASUS UX362FA - repair

[Petr Nosek]

Hi,

  I bought laptop ASUS UX362FA:
https://www.asus.com/2-in-1-PCs/ASUS-ZenBook-Flip-13-UX362FA/

  The sound didn't work. I was looking for solution and I found this
article:
https://forum.manjaro.org/t/alc294-analog-audio-card-detected-but-no-sound-internaly-or-headphones/54089/29

  So I added this line into (
https://github.com/torvalds/linux/blob/master/sound/pci/hda/patch_realtek.c
):

  SND_PCI_QUIRK(0x1043, 0x13e1, "ASUS UX362FA", ALC294_FIXUP_ASUS_SPK),

  behind this line: SND_PCI_QUIRK(0x1043, 0x10a1, "ASUS UX391UA",
ALC294_FIXUP_ASUS_SPK)

   And recompile kernel and it works. I'm sending this report for others,
who have the same problem with this laptop version. Please add this repair
to kernel for the others.

  Thank you.

For repairing it is neccessary to compile kernel. I'm sending solution for
other and if is it possible, please add it in ubuntu kernel.

I reported bug (and solution) also there:
