    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:

    Re: Sound doesn't come back after hibernation

    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.

    Re: Sound doesn't come back after hibernation

    A possible 'messy' fix that works well on my system 9proving that Ubuntu DOES know how to suspend 'PROPERLY' ...

    is to simply tell Ubuntu to "PAUSE", and when it does it will give ONLY one of two OPTIONS, Quit or Suspend, then Suspend works for me with the sound coming back on through the HDMI

    Just a messy fix but works

    Always Trying to Help, Mark

    Good Luck, Mark
