I had a little free time, so I decided to play a little with alsa. I copied the mic verbs from the old model to this new one and it seems to be working fine. Here is the patch for that

Now, the only 'broken' thing is jack sensing, it just mutes front, but not LFE. I guess this is an easy to fix issue.

The mic worked with model=acer-aspire-4930g, maybe you can "copy" the information from that model or something?
Will have to see whether copying both internal-mic related verbs from the 4930g model helps, indeed. I found the arecord message rather disconcerting though. Also, while I have remote access to he 6530g its owner is not feeling well and she can't help me run further tests.
Sorry, no further patches tonight.

P.S. And I blame my e-mail client for swapping my From address around randomly.
