Ok, so I sent some emails to the author of the patch. He suggested me to try kernel v3.9 since drivers are quite different. But since installing custom kernels would avoid me for receiving support, I cannot do this for now. He also suggested hda-analyzer, but as I'm not really a tech-guy, I rather keep my hands off there since I wouldn't know what I'm doing. Another suggestion was to figure out pin configuration, again, above my possibilities. So, I guess it'll be another 6 months until new kernels are provided from Canonical... But, if there's still the possibility for a turnaround, please let me know, and how can I help. Thanks.
