suggestion #9 solves partially the problem because introduces others. I try to explain what happens in the Output audio page :
kernel 3.8.0-22: Devices: Speakers + Analog output (no Headphone when they are connected. To make it work I have to unmute the speaker through alsamixer) kernel 3.8.0-22+#9: Devices: Digital output(S/PIDF) + Analog output + Headphone if they are connected. The fix solves the headphone problem but the volume is low I think because the output is Analog output and no output at all for Digital output(S/PIDF). Sometimes the system boop up without audio because the digital audio is selected. kernel 3.9.2/4 Devices: Speaker (every thing is working fine and is the one I will continue to use waiting for a bug fixing) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1158909 Title: [HP Pavilion dv6 Notebook PC, IDT 92HD81B1X5, Black Headphone Out, Front] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1158909/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
