Bug Description
Ubuntu version: Ubuntu 16.10 and a fresh install of 17.04 and even fedora F25-WORK-
Device: acer predator: G9-593-7757 15,6"/i7-7700/32 GB RAM/512 GB SSD/1 TB HDD/GTX1070
expected: sound comes out of both left and right speaker and the subwoofer
what happened instead:
Sound only comes out of the left speaker or subwoofer.
More system information:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC255 Analog [ALC255 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
audio chip (on motherboard): VGA Chip nVidia N17E-G2-A1 GP104-725-A1
note that that is only 1 device, one would expect several here.
I attempted to fix this by modifying the /etc/pulse/

but this did not work. I also tried various other permutations to see if changing the order of front-left,
Note that the speakers work perfectly fine on windows 10.
Looking around online there seem to be a lot of problems with acer predator laptops and sound on ubuntu.
