For the computer I'll be using an optical cable to connect to the receiver and use that for sound, that way it doesn't require the TV to be on. I guess games don't use the high-end sound technologies that HDMI provides so it's good enough, I was just hoping to not have to use an extra cable, the back of my desk looks like a jungle as it is.
I guess it would make sense if you knew of my setup, although it's a doozy and probably needs a diagram, but here goes: I have two screens, one 24" PC monitor and one 32" TV. The computer is connected to the monitor by a DVI connector (it doesn't have HDMI) and to the receiver by HDMI, which in turn is connected to the TV by HDMI as well. I use the monitor for everything but games since (despite its lower resolution) it's much sharper and easier to read text from. When I want to play games (like Borderlands 2) I switch monitors to the TV. So I still need to have sound when the TV is off and I'm just using the monitor. As I said, the receiver doesn't seem to accept that it's okay to play sound without the TV on when they're connected by HDMI, hence the bypass with the optical cable. I watch blu-rays with my PS3 which obviously has its own connection to the receiver, and since videogames don't use the high-end sound technologies that HDMI provides (as far as I know), SPDIF should be sufficient for video game surround sound.
The "RFM" comment was about the speaker setup. If it's not in the manual (or really the AVRs Setup Menus ... just explore) ... you can't do it.
What you have here is most likely a computer problem. Welcome to the world of HTPCs.
My system doesn't work like that. You can turn off all displays attached to the Onkyo, and the audio keeps playing. Now, I do have a Gefen HDMI Detective Plus attached (for a different reason) but I don't remember having the problem you state without it either. If interested in the Gefen HDMI box, search my threads.
On my system, the HTPC only sees the Onkyo ... not the TV.
Here are some things I have discovered over the years:
- With HDMI off the PC ... Win-7 (and fairly current video drivers) is better. I like using ATI-AMD cards. I'm getting 7.1 Digital and 5.1 PCM over HDMI.
- When using HDMI Audio and Video, the sound card is not used... the video card does it all (at least that's the way it works on ATI-AMD).
- If using HDMI use it for Video AND Audio. If using SPDIF, marry it with DVI video instead (use a $3 (PC) DVI-to-HDMI (AMP) converter if needed).
- Only HDMI can handle multiple PCM tracks (like surround sound channels from games). Games send PCM (not digital bitstreams like DD5.1 or DTS ... like DVD or Movie File). If using SPDIF, you are only going to get PCM stereo in games. Now, the AMP can simulate a "surround effect" from that ... just like it can with any stereo source.
I don't use it, but I also suggest you turn off HDMI-Passthrough on your system. Audio from only the AMP's speakers. If AMP is off, Audio DOES NOT play from TV's speakers. If you ignore this advice (or need the feature) you might end up with some dependency on the TV ... Not sure on this, but just thinking.
HDMI can be tricky because all the HDMI devices in the chain can affect system. HOWEVER, once you see what you can do with it when it's working ... you will never go back to analog or SPDIF.
