Tutorial GameVibe Manual

Looks like the DCS plugin is not set up to send any data to Vibe so that is big bummer. If I was smarter, I would totally offer to help develop something for it. So for now I am focusing my efforts on Project Cars 2, which should work.

I think you are right @yobuddy because the music that plays in the Oculus "home space" will play music through the HDMI cable to the headset just fine when I am testing the vibe settings. As soon as I launch a game in VR mode is when it goes down hill. If I launch PC2 in desktop mode and then go into Rift and run the virtual desktop it works fine.

Another thing I find odd is that I can't get my Sound Blaster Z card to isolate channels correctly, but I still have a few things to research and try on that front before I start asking for help there.


If anyone has vibe and Oculus running together correctly would chime in I'd love to know how you have your audio devices set up.

How do you detect lack of channel separation?

Just FYI, I just changed my card for Vibe to Sound Blasterx EA-5, which has pretty high end specs, but when I run sound check in Vibe, I see amp lights of channels that should be off indicating some (tiny) signal. I am not audio hardware engineer, but my guess minijack itself allows a bit of leak. Just thought I'd share before you throw money into hardware.

Hi @yobuddy,
I changed my audio card in hope of resolving crashes (previous one was no longer supported by Creative). But I still get GV crash sometimes:
Application: GameVibe.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException

I completely understand you can't reproduce this issue, and it is most likely some combination of things specific to my PC, but I still hope you could keep this thing in mind for the future. I went to complain on SlimDX github but last contribution there was 8 years ago, so it is getting quite outdated...

Cheers!

PS: my previous diagnosis was incorrect, I have no idea what causes crash to reproduce

There's nAudio library https://github.com/naudio/NAudio that we use in Crew Chief, but to be honest we've seen situations when it does not work well (default .NET audio is most reliable and lightweight, but is not flexible at all, it won't work for GV). Upside is that nAudio is newer than SlimDX. But I understood your point - if I am not happy with SlimDX, I'll have to implement plugin myself, because SlimDX works for most people. And yes, problem is startup, there's something wrong there.

Good to know you explored that direction. It is kind of low level'ish, and needs a lot of effort to get clean and right, but I hope maybe we will see something like an option in the future, where users can choose what audio engine to use. At least on paper nAudio seems promising as it supports ASIO, for example. I'll try to get a dump of my crash, maybe it'll give a hint why SlimDX/Xaudio2 crashes, really annoying issue, I really like SimTools otherwise, and do not want to get SimVibe.

BTW, one more suggestion, would it be possible to add a button to Game Manager, to turn off motion? That's handy for transducer setup

that button, disonnects evertything. I'd like button to keep vibe, and turn motion off.

I recently setup GameVibe with four Dayton Audio exciters to run RPM effect with Automobilista 2, and I'm having a weird issue: While driving there is a distinct "snapping" noise/distortion which is quite loud and occurs at a regular interval (less than 1 second apart). When I press the "esc" key while driving, and get to the initial pause menu, the snapping noise stops, and the exciters rumble without any issues on the pause screen. Besides this obnoxious noise, everything else seems to be functioning just fine. Anyone have an idea how to fix this?

I have not. I can give that a shot and report back. Any specific recomendation for make/model?

While I await the USB sound card, I took a quick video of the distortion/crackling noise. I apologize that you have to turn the volume way up on the video. My original estimate of the frequency was way off; it crackles/snaps multiple times per second. The noise stops on the pause menu as you can see, but the transducers continue to rumble at the correct frequency. Quite perplexing.

Thank you for the reply. I am in the US, so I ended up going with

Also, I know the manual says to use a quadraphonic setup, but if I am only using a two channel amplifier for my transducers, can I setup things as just stereo? I tried it this afternoon, and didn't notice any difference, which means the crackling/snapping was not resolved, but I was wondering if there were any other potentially adverse effects from using a stereo setup rather than the quadraphonic in the manual.
