Alex, thank you for a great patch! Everything worked as you said. However, I think the noise problem is still here. I'll check on my reference headphones tomorrow, and post. Moreover, setting model=mbp3 doesn't seem to fix the noise issues any more. Is that possible, or am I just confused?
It would be lovely to have the headset microphone work, too. Can I help fix that in any way? If you provide some pointers, I can try to gather the relevant information under OS X, or to experiment under Linux. I'm pretty happy with C debugging and development, just don't know the ALSA stack. If the only thing that's blocking you is the lack of a headset, I'd be happy to help too. I noticed one other issue, which is probably not ALSA-triggered. There are volume sliders for "Surround" and "LFE". I have no idea what "Surround" is -- it didn't do anything that I could notice. LFE is the subwoofer (low-frequency emitter) -- btw, it would be nice to have a better mixer name for it, if that's easy to fix :). The problem is this: if I use the GNOME volume control (which goes through pulseaudio), and turn the volume all the way down to 0, then hit mute, then LFE and Surround suddenly get set to 0. The only way to get them to return is to turn the volume up to a nonzero value, and then toggle mute twice (or use a full mixer). Seems pretty mysterious to me. The bad thing is that this results in people unexpectedly losing all their low frequency sounds -- I doubt many people aside from me look at alsamixer. Let me know what you think about the outstanding 3 issues. If necessary, I'll create separate bugs for them. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
