    Hi,

    Put Windows 7 on Vaio 620n. I get audio (through HDMI) but only 2 channel.
    In the driver window it says Max number of channels 2/ HDCP not supported.

    When I play a channel mapping wav file, everything is mapped to the front of my system.

    Im using the Nvidia Vista driver that originally came with the system. Because every other driver I find is useless. Amazing that Sony is so behind as far as Windows 7 driver support.

    So I guess my question is: is anyone in a similar situation having more success than me - and how?

    Same behavior here. Got a Z21ZN running 7 RC1.

    The problem is not the Nvidia driver but the Realtek Audio Driver.
    The Microsoft Audio driver seems to only support 2 channels over HDMI.

    When I installed Reatek audio driver, it's even worse: the HDMI is stated as disconnected even with the cable plugged in ! I guess our best bet is to get proper Realtek Audio driver from Sony, but I couldn't find it yet, so I stay with MS driver and only Stereo over HDMI :-(

    it's the same for other OS as well. What will you do if the OEM don't make the drivers for their devices for that OS?
    @jprenaux: when did you come here lol? It's vannhi from hfr

    I still have this problem even after updating my BIOS and Nvidia drivers. Can't seem to find any updated Realtek drivers.

    Anyone else??

    Have you tried using the drivers from realtek's website? The recent ones (2.35) worked fine for me.
