Also, what happens if you apply the patch below?
spec->set_widgets_power_state = set_widgets_power_state_vt2002P;
//spec->set_widgets_power_state = set_widgets_power_state_vt2002P;This helps as well. Yay! Thanks :) Whatever the outcome, I have them back more or less (more, for me) properly.
OK, then we know the place to fix now. Try the patch below instead. Does it fix the problem as well?
Sadly, no. Now there is no headphone output at all. Not even to the alternate PCM.
Probably unrelated, but I better mention it anyway: the "Auto-Mute Mode" works strangely, it never mutes anything but headphones. It might work as designed, but it is useless in this case: one still has to mute the speaker manually when plugging headphones (or do something with input events, which I failed to get to work).
Does the problem still happen with the patch?
Well... Kind of no. As I said, there is no headphone output, BUT the laptop built-in speakers ARE muted when the headphones plugged in.
And "Independent HP" has absolutely no effect, which is probably as it should be on this laptop.
With the independent HP turned on, there should be no output to the headphone through the normal PCM. There is a secondary PCM device, and this is routed to the headphone when the independent HP is on.
Ah. I misunderstood (miscounted?) the playback PCMs: this card has three (VT1802 Analog, VT1802 Alt Analog and ID 2806 Digital), the last one being HDMI (just deconfigured, while I was trying to figure the headphones out). The first two named appropriately (if one looks at them), and when tried (hw:0,2. Strangely, there is no hw:0,1) it indeed works (with the revised patch. Not with this one).
