    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
    Code:
    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:

    1. Anyone has an idea why this is happening based on the error message or the "solution"?
    2. Anyone has a way to automate the "solution"?
    3. Any other insights?



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


    Bonus:
    If I set
    Code:
    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:
    Code:
    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`:
    Code:

    when you adjust alsa it works ; but do you store your new settings in alsamixer?

    Code:
    alsamixer store

    Well, adjusting alsa doesn't make it work, what makes it work is deselecting it and selecting it in pavucontrol. Only then I have to adjust it in alsa, but that itself doesn't get the sound back.
    Anyway, I also tried to do `alsactl store`.
    Thanks for your reply though.
