On UNR 9.04 on the Lenovo S10, this seems to be related to bug #312403. When I change the line on /etc/modprobe.d/alsa-base.conf from
options snd-hda-intel model=basic to options snd-hda-intel model=lenovo the speakers mute properly when I insert the headphones, but then the internal microphone stops working. -- Laptop speakers do not mute when using headphones https://bugs.launchpad.net/bugs/109838 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
