I'm using it.
I must wait for a patch, hoping in Takashi? :)
I think i will make some experiment on patch_realtek.c :)
For the noise problem if i understand a little, could be a connection
problem, i will try to graph it.
For the capture problem i need to read more :)

Seems to be a common problem from 2.6.37 with 267.10 driver, for the
moment i will hope this does not create any problem.
I'm not using hdmi on Mobo neither the one on Video card.

This mean that tecnicaly my sound card/motherboard must work with the
patches that Takashi commited?

I disconnected the front panel, before install windows 7 to test if

Takashi if you need debug or something else just ask.
