Comment 117 for bug 1653456

Before I submit a bug to Alsa-devel mailing list
http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
let's clarify a few things:

ASUS G752VS laptop has two stereo speakers behind the display on the rear side of the notebook, and a separate subwoofer that sits on the underside.

1)
If within sound settings the "Analog Stereo Output" mode is selected, the subwoofer doesn't work and its volume control is grayed out (disabled) - is this a bug?

2)
If within sound settings the "Analog Surround 4.0 Output" mode is selected, fade control works even if laptop doesn't have both front and rear speakers - is this a bug?
The subwoofer works but its volume control is grayed out (disabled) - is this a bug?

3)
Microphone jack doesn't work.

4)
Apparently, the headphone jack doesn't work too. But instead of simple universal headphone jack, we must use a proper 3.5mm S/PDIF jack. Can anyone please confirm that headphones doesn't work even with this special type of jack?

5)
The right side of the laptop (area around audio jacks) is pretty hot compared to the left side which is completely cold. I don't use headphones, and
