Public bug reported: Hi,
I come from Windows :( Vista :( :( but now I'm on Ubuntu :D I have this issue, sound only comes out from the left speaker. Almost all the time. I have played a lot with speaker-test, alsamixer, gnome alsa mixer, etc, and all seems well, except no sound from right speaker. I did a change in my alsa conf file, adding this line: options snd-hda-intel model=acer as per instructions found everywhere, namely here https://help.ubuntu.com/community/HdaIntelSoundHowto http://doc.ubuntu-fr.org/acer_aspire_7720g Sometimes, the sound works - but literally with me doing nothing, i.e. just watching a movie clip, the sound will go off in the right speaker. Most of the time, no sound comes out of that speaker. Almost everything else works beautifully. yves@YvesPC:~$ lsb_release -rd Description: Ubuntu 12.04.3 LTS Release: 12.04 yves@YvesPC:~$ ^C apt-cache policy pkgname : N: Unable to locate package pkgname ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1.1 ProcVersionSignature: Ubuntu 3.8.0-30.44~precise1-generic 3.8.13.6 Uname: Linux 3.8.0-30-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.8.0-30-generic.
