This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1869062

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

NOTE: I am NOT the originator of this bug report,
       but have a similar(? identical?) problem.

My machine is an Acer Aspire E17 E5-722-425Q,
and the built-in microphone (and also the mouse pad)
has never(?) been detected. (Since I use a USB mouse
and a USB headset-with-microphone, neither problem has
ever bothered me in the slightest.)

Sometimes, the built-in WiFi is not detected (as is the
case at the moment), and, usually, the built-in Bluetooth
is not detected (also the case at the moment). However,
I *have* observed that, at least in the case of the WiFi
(the Bluetooth is not-so-clear) it seems to be related
to the temperature (especially the external (ambient,
i.e., room temperature)).

Whilst no measurements have been made, if the ambient
temperature is sufficiently cool (cold, actually, PROBABLY
less than 10 degrees Celsius (estimated)), the WiFi is
frequently detected. When it is warm, it is much more
hit-and-miss. (There are some circumstantial reasons to
think, for both the WiFi and Bluetooth (both are USB),
that if there certain unclear external USB devices are also
attached when the system is booted, than one or both is
detected. Apologies for being quite vague here, I have
never tried to confirm or characterise this incidental
observation.)

Attached is the RAW report generated by apport-cli(1);
I do not know how to automagically append it to a bug
which I did not originally create. However, please
note that, at the moment, neither the built-in USB WiFi
nor the built-in USB Bluetooth is currently detected
(and the ambient temperature is currently quite warm).

Follow-up to #2 (again, please note I am NOT the originator of this report).

Searching through some old notes/logs, I found the attached information
about _my_ WiFi H/W (excerpted and slightly redacted because I have not
checked the complete notes/logs for sensitive information). Abbreviated
summary (from `hwinfo --all', see attachment for more details):

Unfortunately, the (less likely to be detected) builtin USB Bluetooth
was not detected. ;-(
