Win7 Audio
-
Apparently, audio in Win7 has been 'greatly improved'. Its been improved so much, it doesn't work in any sensible fashion. To me, audio output from my machine should be a single, global thing I don't want to control volume levels for lots of different apps - I want a system volume! Anyway, that's just one problem... I just got a new machine and I have three monitors. Left is on HDMI, centre is on DVI with audio to rear jack, right is on VGA with audio to front jack. I was hoping to be able to have sound from all three monitors simultaneously, but it doesn't seem possible. From the Realtek control panel I can listen to all six speakers fine, but I only seem to be able to get the HDMI and one of the other monitors playing simultaneously. I had hoped to route stereo left to the left monitor and right to the right monitor, with the centre balanced. Is the best I can get left and right on and centre off? EDIT: Actually, even with the HDMI playing simultaneously, there is a noticeable delay, so I'd also need to be able to control the audio output timing...bah! Might as well stick to one monitor!

And you're blaming Windows for that messed up setup?? Seems to me that would be the fault of Realtek for not supporting your completely screwed up audio requirements.

No it's Windows. It can't output the same audio stream to all audio outputs at the same time. Why ever not? The Realtek panel proves I can get output to all six speakers, just not the same output at the same time.
Is it windows or the HDMI chip on the monitor?

2009 called, they want their New OS Teething issues back!
Well fads they come and fads they go. And God I love that rock and roll! Well the point was fast but it was too blunt to miss. Life handed us a paycheck, we said, "We worked harder than this!"

That doesn't point to Windows to me. I've had too many problems with RealTek drivers to know better. Download the latest driver from RealTek and see what happens. Don't use the ones that came with the motherboard.

Did you tell them about Japan?

I suspect you're screwed on getting multiple outputs synchronized (unless you spend $$$lot$$$ on an audiophile card); the problem is almost certainly the monitors themselves. Video decode takes a non-zero amount of time, and a number of preprocessing options that help the LCD work display content better add additional variable amounts of delay. The monitors themselves are probably delaying the audio passing through by an equal amount so that when watching a video the image and sound remain perfectly in sync.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

I strongly suspect the issue is Realtek. Cheap sound devices frequently have cheap drivers, that don't fully support what you want to do. Sounds like a hopelessly messed up setup anyway, what on earth is your use case?
