I have recently purchased a Yamaha RX-V463 receiver for my home theater. It has HDMI switching but I cannot get the audio to work when I play bluray movies from my computer through the amp to my tv. The video is fine but no sound. I can get analouge audio via the 3.5mm audio jack to work but the quality isn't fantastic.

Laptop -> TV via HDMI works fine for video and audio Smile

Laptop -> Amp via HDMI -> TV via HDMI works for video but not audio Frown

My laptop (dell xps16) claims to be able to output dts and dolby digital but when I run the test tone I get the message "Audio format not supported, Could not play test tone" or something to that effect.

If anyone has any advice or a solution that would be great.

I am dowloading the lastest realtek ATI HDMI codec pack so I will see if that has any effect.

Would have to confirm, but i'm fairly sure that model has only HDMI switching (basically an HDMI switch built in to the receiver - has no connection to the receivers internals apart from the receiver controls the switch). So yes you will need a separate audio feed. i'd return the receiver for higher spec'd one (with HDMI upscaling) if funds allow.

Thanks for the reply,

I explicitly asked they guy at Paul Money whether the amp would pull out the audio and play it through my surround system and he assured me it would. The manual confirms you can do this (you can select between analouge or HDMI audio inputs). I think it is more of a problem of the amp not recognising the ATI graphics card audio output format although the amp decodes DTS, the format being output.

I have read of a number of people having this issue with Denon and Onkyo receivers as well... Apparently Yamaha was in the process of upgrading their firmware to fix the issue.
