Thanks a lot! Nice to see some movement on this.

I was able to get audio to work on an Aspire 8930G using the attached patch, including routing all speakers. However, I could never get any DACs other than the first two to work. I've been holding off on making a real patch to add full support properly until I fix this issue.
Can you test the patch? For me, only Front and Rear work, not Center/Sub.
Hmm, I applied the patch to the latest git, selected model acer-aspire-4930g, upped volume in the mixers and ran: speaker-test -c6 -Dplug:surround51 -t wav -l1
Got only front left / front right output. What am I missing?
I'm currently using a nasty hack which routes DAC 0 to both Front and Rear and DAC 1 to CLFE and some asound.conf magic to make it sound decent, but it's 3.1 sound, not 5.1.
I managed to get hda-analyzer to work and confirmed that the audio does get to the DACs (if I configure the Rear DAC to the CLFE stream dynamically it does work), but "something" is making all but the first to DACs not work. It could also be the mixers attached to the DACs - the actual audio outputs are okay because I can route them to the working DACs and get output. I've tried tweaking everything and ensured that everything was turned up and unmuted, but I've run out of ideas.
Am I supposed to adjust anything with the analyzer before testing your patch?
Kind regards, Jin
Recently I've also tested the three audio jacks in 5.1 output mode. Same problem - the CLFE *output* works but I get no sound unless I hack the routing to connect it to the other DACs.
I'm starting to suspect that there's some proprietary Realtek init missing - maybe some tables or something related to the "encryption module".
Here's a little render that I made of the codec routing: http://marcansoft.com/transf/codec.png
