I should note that in alsamixer, the headphone slider is always disabled, even when the heaphones are plugged in. To be more precise:
Before headphones are plugged in: Headphone slider: disabled Speaker volume: N% (say, 75%) After headphones are plugged in: Headphone slider: disabled Speaker volume: 0%. As the original reporter mentioned, it happens regardless of whether or not the AutoMute feature is enabled or disabled. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
