Side note: There might actually a better solution in newer kernels: if you install the daily DKMS package ( https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS ) you will get this too.
Then edit /etc/modprobe.d/alsa-base.conf and add this line: options snd-hda-intel jackpoll_ms=250 ..then reboot and test. In case the sound card is not the first hda intel sound card, you might need to add more, like this: options snd-hda-intel jackpoll_ms=0,250 or options snd-hda-intel jackpoll_ms=0,0,250 ...depending on which card you want to change. -- 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/874535 Title: Volume Slider Jumps, due to rapidly changing hardware jack sense state Status in “alsa-driver” package in Ubuntu: Triaged Bug description: In Oneiric Release, The volume slider randomly jump down a notch or two for fraction of a second, even when there is no audio playing on the system. If mute is selected, the menu will quickly flip out of mute mode and back again. This change actually affects the audio output, resulting in pops correlated with the volume changes. nVidia GF106 Audio Controller --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
