It has now been the third time I got problems with the sound while working on a Linux Os in a dual boot configuration with Windows 10. It happened to me twice under Ubuntu 16.04 and most recently under Debian 9.0.1.

It appears that after any random system suspension and/or lock screen with headphones plugged in, the sound card recognition stops working, and when I unplug and plug the headphones again I no longer get an answer from pulseaudio. After reboot, I get Dummy output in linux's pulseaudio and despite trying many solutions, the only really viable one is to format the disk and make a clean install of both OS. I even tried to restore the disk images and it didn't work.

I wanted to ask how is it possible that a linux sound problem can affect Windows 10 in a different partition, and be persistent over disk image restore? What might be causing this problem?

I have a Dell Inspiron 7560, the sound device is Intel Corporation Device 9d71 (rev 21).

Thanks!

    Your details are misleading as no configuration change happens when you plug and unplug headphones. This means that the only possible change is at a lower level such as plug&play/ACPI/hardware issue. Can you confirm that the problem happens after you shutdown the computer completely from Linux and reboot into Linux? Such hardware (plug&play/ACPI) conflicts between OS's are not that uncommon. – Julie Pelletier Jul 2 '17 at 3:13
  • To amplify @JuliePelletier 's comment, "shutdown the computer completely" means "turn off the power for more than a few seconds". – Steve Jul 3 '17 at 16:10
