Public bug reported:
Bug seems similar to another reported bug with Alienware 18 laptops. It
should be Realtek ALC3661 however it shows up as ALC668. Sound only
comes out of 1 Channel, which appears to be subwoofer. Unlike the other
bug, closing the lid appears to have no effect on sound.
When doing the bug test, it said sound would alternate between 2
channels, however I only heard one consistent sound. It did not
alternate. I believe it is playing from the subwoofer only. I would love
to know more about how to route the sound to the proper speakers.
I attempted modifications to daemon.conf in pulse and .asoundrc but have
not found the correct configuration yet.
This laptop is equipped with 2.1 Surround and should play sound
accordingly. Also, alsamixer only shows (1) speaker control, whether
this is normal I am unsure.
