After fresh installation even stereo configuration is set. From the menu can be selected 4.0 configuration making the rear left and right speakers work, however, front center and LFE (subwoofer) do not emit any sound in any application. They can be only tested (and they are working within this command) by `speaker-test -D default -c6 -twav`.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
Thank you for your help.
