[pvrusb2] Hauppauge HVR-1900 - PAL-Nc, no audio

Hi all,

Having an issue with PAL-Nc channels (received via cable in Argentina), using the Analog tuner of a HVR-1900.  Video is working very nicely, but there's no audio.

I'm running the latest snapshot of pvrusb2 that I could find (pvrusb2-mci-20120219) - because the version that came with my distro (and likewise the v4l version) don't seem to have the necessary changes required to support PAL-Nc (specifically the PVR2_ENABLE_STDADJ changes in pvrusb2-hdw.c which seem to be required for PAL-N/Nc).

When I plug in the usb I get:

This produces the following mpeg, without audio:

Is there something I can do about this?  Any guidance would be greatly appreciated.

btw: I know the hardware is capable, because this works under the supplied WinTV software in windows.

Thanks in advance,
