Hello @ all,
I'm Rüdiger from Germany. I'm no programmer, that's my biggest fault here. But because of a "private" problem with ALSA and Intel HDA I want to help whereever I can - at least with that special problem.
I'm running a Lenovo ThinkCentre A58 with a ALC662 rev. 1 chip on board. The mainboard has 3 jacks at the back of the PC and 2 ones at it's front (mic and headphones).
The problem is, that the connectors are not automatically arranged to playback 5.1 surround sound. I must manually set the "model" to "asusmode4" to get 5.1 and then run a script as root, to set the backside jacks to output and to Center/LFE and rear speaker. Also I have to mute the internal speaker.
I've tried to patch the module manually, but this went wrong somehow. I don't know how to proceed.
So maybe you can help me and I can help you to complete the ALSA code for this special mainboard/PC - hopefully.
So long, I would thank you for your feedback.
Regards, Rüdiger
