On Ubuntu 12.04 LTS, I solved this issue perfectly on the Vostro 3750 simply by updating to the latest Realtek drivers from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#High%20Definition%20Audio%20Codecs. (this page is referenced from https://help.ubuntu.com/community/HdaIntelSoundHowto, scroll to the end). In my case I had to patch the install script given in the Realtek package (I had version 5.18): tar -xvjf LinuxPkg_5.18.tar.bz2 cd Rt-Linux-HDaudio-5.18/ ... then edit file 'install', and change the line cd alsa-driver-RTv5.18 into cd alsa-driver-RTv5.18/alsa then run install script: sudo ./install reboot for the changes to take effect (I guess you could try something like "sudo alsa force-reload" instead). Afterwards, plugging / unplugging headset should work flawless. Also these new driver should handle better the bass speaker on the Vostro 3750 (now the bass speaker and speaker volume are sync'ed - in alsa mixer, there is actually no more separate volume for bass speaker, just a toggle to enable / disable it). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/978880 Title: [Dell System Vostro 3750, Realtek ALC269VB, Green Headphone Out, Left] volume slider problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/978880/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
