I upgraded my ubuntu from precise to quantal to ensure this bug is fixed at this ubuntu version, as it is the only one(video and keyboard+mouse issues had workarounds) I hadn't found a workaround for my 12,1 imac from the huge amount of information I researched upon. I consider I'm done with research already.
The sound card codec is Cirrus Logic, the snd-hda-intel models for that are imac27 and mbp55, I tried both, which results in internal speaker sound as usual, thought it too gives speaker sound even with a headphone connected to the imac 21,5(the headphone still does no work by the way); the mac book pro and imac 27 have a different number of connectors comparing to a 12,1 imac which have around 9 connectors(counting thunderbolt, headphone mic and output, usbs ans such). I tried using the latest ubuntu audio packages(throught their ppa, no advanced stuff), updated kernel(only the 3.3.7 stable one works), the snd-hda-intel thing and countless others(muting and unmuting for example). It seems this issue isnt fixed on Quantal, care to mark this bug as affecting it? Maybe it can get more attention being related to the future ubuntu version(the perfect time to report and fix bugs is now). Also PLEASE let me know of a workaround for the headphones not working at all(just the internal speakers) if you know of any or have the knowledge to devise one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003039 Title: No sound in headphones on imac 2011 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1003039/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
