Odd that only one speaker would require such a special handling, but I guess it is what it is. In the meantime I found a more pressing issue where I also failed to find a solution: Pin 0x1b is resposible for rear speakers and at the same time for external headphones. If I set the pin to "headphones" in hdajackretask, then I "lose" the speaker and can't select a 5.1 profile. If I set it to internal "speaker", the way I have it set up now, then sound comes out of speakers and headphones at the same time. "hdajacksensetest -a" will detect presence even if sensing is disabled in hdajackretask, so I assume that this could be somehow used to mute the speakers, but I was not able to figure out how to approach this. This is quite an issue for audio conferencing, so I'd like to tackle this first and leave the LFE problem for later. What would be the best way to solve this, how should this pin be configured?
