> I tried to re-submit the bug report but I am not really sure what the alsa-base.conf should look like or how to reinstall/overwrite.
These commands will replace your alsa-base.conf with the original one: sudo mv /etc/modprobe.conf/alsa-base.conf ~/alsa-base.conf.old sudo apt-get install alsa-base --reinstall Otherwise I think Raymond is right, you need to experiment a bit with hdajackretask (in the alsa-tools-gui package) to find the internal speaker, because BIOS does only indicate 0x14 as speaker - and that's probably the subwoofer if that's the only thing you hear audio from. -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to alsa-driver in Ubuntu. Matching subscriptions: Ubuntu Studio Bugs https://bugs.launchpad.net/bugs/1332900 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.
