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 Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/978880 Title: [Dell System Vostro 3750, Realtek ALC269VB, Green Headphone Out, Left] volume slider problem Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: When headphones plugged in there is no sound. To get sound in headphones i have to go to alsamixer and raise volume level on SPEAKER slider (MM stays on) and sound in headphones is back. This works untill system is restarted or headphones are plugged out and plugged back in. After restart or replugging headphones i must go to alsamixer again to get sound in headphones. I tried disabling AutoMute in alsamixer but this doesn't help.
