Audio with PVR-500, but not HDHOMERUN

[rnmixon]

I finally figured out how to unmute the IEC598 source source and I not get optical SPDIF sound for ONE of my sources (Hauppage PVR-500 svideo 1 port). But both of my HDHOMERUN sources only show video, no audio.

Any ideas on what gives? I'm using the ASUS M2NPV-VM motherboard with build-in nVidia video, the extra SPDIF bracket.

I've got my cable box svideo port hooked to svideo1 on the PVR-500, my antenna is split/amplified before feeding the two ports on the HDHOMERUN. I was hoping to have three sources - with OTA HD on the HDHOMERUN sources.

thanks - Richard
