I can get audio using either of the two headphone jack connectors (middle and right connectors) in my headphones (ordinary in-ear headphones). A google search on S/PDIF mentions that some laptops have a combined S/PDIF and headphone connector socket, which is likely to be one of the jacks on the front panel.
With alsamixer: Speaker -- effects the internal built-in speaker volume Front -- effects the volume of the headphone jacks Master -- effects both Speaker and Front volume So for me, alsa/alsamixer are applying the volume correctly. Also, the jack detection was working with Ubuntu before the switch to pulseaudio, and worked on the Vista setup that came with the machine. I will try the suggested fix on the other defect to see if that works for me as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/870360 Title: [HP Pavilion dv7 Notebook PC, IDT 92HD75B3X5, Internal] Speakers not disabled when headphone jack plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/870360/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
