[Bug 1332900] Re: [Alienware 18, Realtek ALC668, Speaker, Internal] Playback problem

 

> One other thing I noticed is upon startup/load of Ubuntu, at the top
of the screen it says something about snd hda codec "module has bad
taint".

This is the alsa daily build module. It is printing an warning message
to inform you that you're running a module that was not compiled with
the rest of the kernel. You can ignore it.

Hmm, maybe this is related to the daily HDA DKMS too, somehow. There has
been some reorganising upstream w r t the devices. Try uninstalling the
daily DKMS again, reboot, and retry.

you say, otherwise how might I get started experimenting with
hdajackretask?

Omgubuntu wrote a small introduction here, not sure how helpful it is:

Yes, thanks.

Title:
  [Alienware 18, Realtek ALC668, Speaker, Internal] Playback problem

Status in “alsa-driver” package in Ubuntu:
  Incomplete

Bug description:
  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.
