Hi again,
after feedback that I'm mostly on my own here because this is not remotely testable I invested quite some time into figuring out what is what and was able to make some progress. Still I am at a point where help would be very much appreciated as I am not sure how to proceed further.
Basically its almost working now, I managed to "connect" 5 speakers, but I can't find the LFE. I tried various combinations in hdajackretask and hda-analyzer, but was not able to get any sound out of it.
My current layout is as follows:
Pin 0x15 Front Left / Front Right Pin 0x18 Center (left channel audible) Pin 0x1b Rear Left / Rear Right, Headphones
I am not listing the mic/line pins here, just focusing on the speakers.
Still need to do some fiddling for 0x1b to make sure the rear speakers get muted when I plug in the headphones, but that's also something for later.
Could someone hint me how to proceed in "finding the LFE"? Where should I be digging? I did also have a look at parser hints documentation and tried some, but this was more a random attempt and did not really help me.
I am attaching my current alsa-info along with the retask configuration that is currently applied.
Kind regards, Jin

Hi,
I am not sure if this is the right place to ask or if I should just submit a bugreport, but you guys helped me out with a similar problem about 10 years ago, so I'll try here first. If I'm wrong here, then I apologize, just let me know.
I have an Acer Aspire Ethos 8951G notebook which has 6 built in speakers for 5.1 surround sound, it's a Realtek ALC669X.
The problem is that only two speakers are recognized by default.
I tried fiddling around with hdajackretast and it does make a difference, but I somehow could not find a step-by-step approach on how to figure out what is what and how to map everything correctly, so some guidance would be very much appreciated. I even ended up in situations where I got channels supporting only mute which would influence muting of other channels, I really got lost there..
Here's my alsa-info output: http://alsa-project.org/db/?f=3adde87164f5fc349c3c78b211ee63e416ebf10b
It would be great if we could figure it out and make it work by default.
Basically that's what we did 10 years ago, back then I had an Acer Aspire 8920G with a ALC889 which had the same problem that got fixed by you and these days it just works out of the box :)
Kind regards, Jin
