Fixing sound on Asus UX534F / some UX533 models

Fixing sound on Asus UX534F / some UX533 models

[Hans de Goede]

Hi Kai-Heng Feng, Takashi,

I see that you are on the notification list for this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439

So you may have already seen this. Some owners of affected
laptops (which have non working speakers / headphone output atm),
have done some heroic debugging work and come up with a set of
2 hda-verb commands which fix this.

I'm not all that familiar with writing hda quirks, so I was hoping
that one of you 2 can come up with a patch to fix this at the
kernel level.

This would also resolve these 2 bugs, which I believe are the
same bug really:

https://bugzilla.kernel.org/show_bug.cgi?id=206289
https://bugzilla.redhat.com/show_bug.cgi?id=1834751

Regards,

Hans

Adding verbs are trivial and it can be done even without patching
kernel but providing by a patch via patch module option of
snd-hda-intel driver.

But, before moving forward, I'd like to confirm about the correctness
(and the safeness) of those verbs.

Kailang, could you check the COEF verbs mentioned in the bug entry
above?


thanks,

Takashi

Hi Hans de Goede,

Please test below.

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

I think Headset Mic will work.

Kailang

Hi Takashi,

hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774

This will enable HP out. Asus more platform use this.

Thank you, and sorry for being somewhat slow to respond.

I do not have access to the affected hardware myself.

I've asked users who have reported bugs about this to test these setting
and report back in the following bug-reports:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439
https://bugzilla.kernel.org/show_bug.cgi?id=206289
https://bugzilla.redhat.com/show_bug.cgi?id=1834751

I will follow-up when I have heard back from the
bug-reporters.

Regards,

Hans

Ok, I've gotten the first feedback. I ve asked the
users to test the following after running the 4 suggested
hda-verb commands:

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)

I've got feedback from a user with a UX533FTC-A8221R laptop:

1. Speakers: works
2. Headphones output: works
3. Internal mic: doesn't work
4. Headset mic: works

So things are looking ok, but we still have some
work to do to get the internal mic to work.

Kailang do you have any suggestions for getting the
internal mic to work?

Regards,

Hans

Hi Hans,

The bellowing was Gediminas Aleknavicius (lektuv) mention. (Launchpad #173)
==>After running the above commands sound and mic works on both built-in and headset with 2.5mm connector. The model is UX533FTC.

Internal Mic was worked.

I see and in (Launchpad #174) there is another confirmation that everything
works, this time with an UX534FTC.

I also got a report from a user in the Red Hat bugzilla about this:

On an UX534F just these 2 commands are enough to make everything work:

hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774

I'm not entirely sure if using the other 2 commands you gave me
are actively causing problems there, or if they just are not
necessary. I've asked the reporter about this.

So it looks like some models need just:

hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774

While others need all 4 commands:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774
hda-verb /dev/snd/hwC1D0 0x20 0x500 0x45
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x5289

Kailang, is that enough to write a kernel patch for this? If not
what other info do you need ?

Hans

A quick follow-up on this, one of the reporters of:
https://bugzilla.kernel.org/show_bug.cgi?id=206289

Still has a problem with the internal mic not working.

He has tried both using all 4 of these:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774
hda-verb /dev/snd/hwC1D0 0x20 0x500 0x45
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x5289

As well as just using:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774

Which some users report is enough for them.
His exact modelis "UX533FTC-A8221R"

Still the 2 / 4 commands (depending on the
exact model) do help for various other users/models
so it would be good to get these added as fixups to
the kernel.

The specific model with the internal-mic issue
will need further examination.

Hans

Thank you.

Kai Heng Feng, can you build an ubuntu kernel with Kailang's patch included?

It seems that most reporters of this issue are in:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439

So if you can post a link to an Ubuntu test kernel there, then hopefully
we can get some feedback on this patch.

I'll attach the patch to the bugzilla.kernel.org bug and ask the
reporters there to test as well.

Regards,

Hans
