Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

After a Suspend, the system comes back up WITHOUT sound of any sort. One system has a Dell SoundBlaster card. Works great normally. Another system uses the on-board HDA chipset and it works great. The third system does the same thing. Used alsamixer settings, killing pulse audio so it can restart, alsa force-restart and a lot of Ubuntu forums, Ask Ubuntu and some super user sites / forums suggested fixes. No luck. What can be done? I am more than willing to work with a tech and troubleshoot the systems.
