Hi David,
I'm currently checking the bug report regarding PA, and this looks like an issue with "Headphone Mic" jack control.
The reported problem is that PA doesn't react properly when both HP and dock line-out jacks are plugged and line-out is unplugged. The machine in question is Dell E7250, and I see that it has only "Headphone Mic Jack" kctl without "Headphone Jack" kctl. Is this the intentional behavior?
Yes. The "Headphone Mic Jack" indicates that the jack can be used to indicate either "Headphone" or "Mic".
Hm, OK, that was the trick. But now I wonder whether this was a right choice. Maybe a more straightforward way (from user-space POV) would have been to create two jack ctls (Headphone and Headphone Mic) and notify both of them.
Not so sure about that. Then you might get two events, and userspace needs to synchronise them, and then understand that it's about the same jack.
I think the current solution is better.
The additional "Headset Mic Phantom Jack" indicates that headset is a third usage for the jack and there is no hardware that can detect which one of them it is. So it looks correct to me.
Also the Dell E7250 is Ubuntu certified, but I don't think docking stations are part of that certification suite (at least not for Dell E7250).
I skimmed through the opensuse bug as well. Two notes:
- Here's a guide of how to generate a PA log, avoiding the autospawn
Yeah, but I didn't want to let user touching the config, as people often forget to revert :) But maybe it's better to mention it, judging from the people's reaction.
- There is a patch series in the pipeline [2] that Tanu has promised
to review, that makes module-switch-on-port-available more aggressive w r t being able to reroute away from unavailable things. I suspect it would help here, but I'm not completely sure.
The last unplug event in the log shows
D: [pulseaudio] module-alsa-card.c: Jack 'Dock Line Out Jack' is now unplugged D: [pulseaudio] device-port.c: Setting port analog-output-lineout to status no D: [pulseaudio] device-port.c: Setting port analog-output-speaker to status unknown
and no activation happened to analog-output-speaker. So, yes, your patchset might cure this. But I wonder why this happens only with the dock line-out and not with normal headphones...
Could be just unlucky ordering perhaps? Does the just pushed patch help?
