I have the same laptop. Installing newer alsa-drivers or the headphone hint do not help. A workaround is the following:
I. install hda-verb. 1. wget http://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz 2. cd hda-verb-0.3 3. make 4. sudo cp hda-verb /usr/local/bin II. install this script: http://hup.pastebin.com/f5ac554d4 1. sudo wget "http://hup.pastebin.com/pastebin.php?dl=f5ac554d4" -O /usr/local/bin/hp-toggle.sh 2. sudo chmod +x /usr/local/bin/hp-toggle.sh Running 'sudo hp-toggle.sh' from console mutes the active sound output and switches to the other. If both are active, the speakers are muted. This is not exactly the same as found at http://digitizor.com/2009/10/22 /fix-headphone-sound-problem-hp-laptop-linux/ but based on it, since that doesn't work with this card. Optional convenience steps: III. create icon on desktop with the command "gksudo hp-toggle.sh", drag in onto a panel if you like. IV. don't require a password for switching outputs. 1. sudo visudo 2. add line: %admin ALL=NOPASSWD:/usr/local/bin/hp-toggle.sh 3. save. -- When headphones are plugged in, the speaker does not get muted automatically. https://bugs.launchpad.net/bugs/477154 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
