Well even though you definitely have the MBP 5,1 (and the same Subsystem & Vendor IDs - which should automatically match to the mb5 model) it looks to have chosen the mbp3 model instead which would only happen if it was overriden when the module was loaded - can you see what the contents of /sys/module/snd_hda_intel/parameters/model is? Otherwise you could change the last line of alsa-base.conf from:
options snd-hda-intel power_save=10 power_save_controller=N to options snd-hda-intel power_save=10 power_save_controller=N model=mb5 and manually specify the model yourself. -- Poor support for MacBook Pro 5,1: noise, no jack sense, no in-line headset microphones, broken volume control https://bugs.launchpad.net/bugs/488103 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
