I can confirm that this is broken ( ie. plugging headphones mutes speakers, but has no headphone out ) for my system too ( Macbook Pro 3,1 / Santa Rosa ). I checked all of the ALSA mixer controls, and wasn't able to get the headphones working by toggling any of the settings and/or raising any of the levels.
I'm currently running the latest & greatest Karmic bits. kernel is: 2.6.31-4 Please see attached alsa-info.txt Note, I tried adding "model=mbp3" to the alsa options in /etc/modprobe.d /alsa-base.conf, but it made no difference. ** Attachment added: "alsa-info.txt" http://launchpadlibrarian.net/29579984/alsa-info.txt -- Headphone jack regression in 2.6.31-1 https://bugs.launchpad.net/bugs/396563 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
