It's apparently three speakers, but only two channels. The sub outputs the merged left and right channels. When I ran the 'ubuntu-bug audio' command the tone test it did wasn't alternating channels in any way.
The !!Sysfs Files section of the script doesn't appear to output anything since the switch to ALSA DKMS. Is there some other way I can provide that information, or is the above from Daniel enough? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1299322 Title: [Alienware 18, Realtek ALC3661] Sound only comes out of subwoofer, and requires lid to be closed then opened to come out of speakers at all Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: To get any sound out of the speakers I need to close the lid of the laptop, let it go to sleep, then re-open it. When I unlock the computer the sound will then work from the speakers. Sound from the speakers is not using all of the speakers, and appears to only come out the subwoofer channel or center channel on the bottom of the laptop. There's no sound from the 'speakers' on the front.
