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.

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
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
