Sound doesn't come back after hibernation

I tried to debug it myself and had some success, but still need some advice in order to solve the problem properly.
The Problem: After I put my computer to hibernation I have no sound (suspend works fine).
My system: HP spectre X360 4100 - Broadwell
The error message: dmesg shows

rt286 i2c-INT343A:00: I2C error -110

The partial solution:
I can get the sound back if I go to pavucontrol, switch to headset and then back to built-in speakers. But it's too loud, I have to open alsamixer, choose the card and lower the volume on master. That will bring the sound back to normal.

The questions:

• Anyone has an idea why this is happening based on the error message or the "solution"?

• Anyone has a way to automate the "solution"?

• Any other insights?

I'd be happy to supply any additional necessary info...

Bonus:
If I set

acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'

on grub, the sound works, and keep working even after hibernation but then there is a problem with the accelerometer, and `monitor-sensor` reports it as "undefined".
When I do that aplay gives different output for the card:

card 1: PCH [HDA Intel PCH], device 0: ALC3242 Analog [ALC3242 Analog]

might be a different approach to solving the problem, but I don't know enough about ACPI...
normal output from `aplay -l`:

Re: Sound doesn't come back after hibernation

Hi!

I think I have the same problem. Thanks for the temporary workaround, the only 1 I have had the time to find previous was to restart the computer every times it happens (it doesn't happen everytime for me).

Next time it happens, I will check my dmesg to confirm if it is in deed the same problem, or if it happens to be two similar but different problems. Will get back then.

(for the record, those time the sound is gone, a large green icon is shown for half a second on the sddm lock screen when the computer returns from hibernation)
