OK, looking at two outputs, the difference is that the recent kernel allows the 5.1 output configuration with two mic jacks. But, this looks rather strange as a laptop. Does the machine have really two microphone jacks? The BIOS sets pins 0x18 and 0x19 are mic jacks.
I feel like this was the issue the LAST time it stopped working, too. No, the system does not have two mic jacks - at least, there is only one visible and accessible to the user on the outside of the case, on my model.
You have three items in "Capture Source", Internal Mic, Mic and Mic 1. Which inputs are working actually? If one of the last two is bogus, we can disable it, then we can the unused pin. For example, a patch to disable the pin 0x19 would be like below.
I don't have a working kernel on mine at present, but if Tormen can't provide this info soon, I'll track one down and provide it. I expect that one of the latter two inputs must be bogus.
