ATI 4xxx, HDMI Audio : questions

[arameth]

I'm building a new HTPC, but have some questions as I've never pushed everything via HDMI before.

ATI 4650 w/ HDMI output to reciever
Onkyo 606 w/ HDMI to TV

So, let's say I fire up a game on the PC...will the sound from a game automatically be passed on to the reciever via the ATI card? Will I need to do anything to get sound from a sound card passed to the Video (and ultimately to the reciever) ?

Also, can anyone see any problems with this setup, or have any suggestions to make this a smooth setup?

Thanks!

I would find another solution. I have an Onkyo SR806 and an ATI 4650 and there are problems. The ATI card detects the receiver as being connected using DVI instead of HDMI so you get no sound. It is a known issue with ATI and Onkyo/Yamaha AVRs.

I have the same video card as you and building my HTPC this coming weekend. I also have an Onkyo 605 receiver. I will let you know what happens I guess.

Will be installing Vista 32 on it and playing my DVD rips from my HD.

From what I understand, ATI is not reading the EDID information from the AVR correctly... The only solution seems to be to purchase a device that reads the EDID info from the AVR and then sits inline between the Video card and the AVR. Problem with that solutions is it costs another $120.

Audio over HDMI is still in it's infancy in regards to HTPCs unfortunately. I never could get my HD 4670 and Denon 1909 to work correctly. I could get video just fine but no audio whatsoever. Didn't work with my 4870X2 either. Hope you have better luck.

I'm assuming that this is only a 4800 series issue. I have a 3450 connected via HDMI to an Onkyo 705 with no problems.

I guess the suggestion then to the OP is to have an optical/coax sound cable handy for the build...until they sort out the HDMI issue.

An extra sound card is handy... I'm having to run my Asus card using optical and DDL. I read in one forum that a user has HDMI working with an Onkyo AVR. He did it by using HDMI 1 (DVD) and a short cable. I'm going to move my HTPC closer to the AVR and pick up a 3 foot cable tonight, using 9 foot now.

afaik the edid problem is mainly with Yamaha AVRs

Well it appears to be affecting my Onkyo 806 after looking at the EDID info in the Registry. Also, the thread over at avforums talks about EDID not reading correctly on the 606. http://www.avforums.com/forums...ed-onkyo-tx-sr606.html
