Monitoring both stereo and surround projects

Ok I've bean serching over the subjects but I can't find anything related.

I've my 6 channels connected to produce 5.1 and stereo events, my question is why I can't listen the low frequencies coming from the subwoofer when editing a normal stereo event. Whith Windows Mediaplayer and in 5.1 mix when I select the LFE, the low frequencies are coming perfectly.

I'm new to Vegas so sorry if this is a dumb question

P4 2.4 HT 800FSB
Asus P4P800
512mb 400Mhz
Sound cart - On Board SoundMax - will upgrade soon
Speakers - Creative Digital 5500

Vegas 4.0e

PS: any hints on sound cart between 100€ and 250€, I live in Europe, Portugal

Vegas does not stream AC3 encoded audio. I don't believe the on board SoundMax card has 6 external audio outputs. Vegas requires that you have 6 discrete analog outputs to stream all channels of the 5.1 mix.

What drivers are you using in Vegas?
How are you routing your master bus in Vegas to your hardware?

Hi Peter, yes it does!! The SoundMax can do 6 discrete analog outputs in to 3 stereo pars, and that's the configuration I have. I sad that I can do 5.1 creating a bus for the LFE and in that case I can hear the low frequencies. But when opening a stereo project the low frequencies from the subwoofer just disapear, only have LR spekers.

I'm not at home so can't remember to were i'm sending the routing, but I tried every routing in the audio options and stills the same.

About the drivers I don't know.

Gotcha.

A stereo project does not send to the center, rear, or LFE in Vegas. So not hearing anything from the LFE of your speakers is expected behavior. If you do hear something out of any speaker other than the front Left and Right, then this is NOT a function of Vegas, but your sound hardware.

To author content for the center, rear, or LFE in Vegas you must work with a surround project. There is nothing in Vegas that will permit you to create a stereo project that provides content LFE channel.

OK, I found this his definetly a hardwear limitation, so I'm looking for a decent sound cart, I've found a very interesting one, counld any of you tell me about compatability or problems of Terratec Phase 28, any one is using it?

Oh! And thanks Peter

This is not a hardware limitation, it is a lack of hardware limitation. In a Stereo monitoring situation there is only 2 outputs used on your soundcard. If you're looking for a 2 speaker plus subwoofer (ie LFE) configuration setup. You need a cross-over network in your monitoring system, where the 2 channels from your sound card get fed into the inputs of the cross-over, and the higher frequency L/R outputs get connected to your L/R speakers and then the Low frequency output feeds the subwoofer.

That's it Rednroll !! So this means that my Creative® Inspire™ 5.1 Digital 5500
speaker system isn't capable of doing that, but whem play some music in mediaplayer the subwoofer works, but not in Vegas.

Thats why I think that must be the Sound Max drivers...

"You need a cross-over network in your monitoring system"

What kind of monitoring system are we talking about? Any brands...
What about the Terratec Phase 28 sound card is it good?

The Media player uses the DirectSound driver. This driver model uses the speaker configuration used in the Sound prefs for Windows.

What you can do is, select DirectSound Surround mapper as your audio device in Vegas. Depending on the driver, you may your stereo mixes to use the LFE by default then in a stereo project in Vegas. However, this is a ghost and completely out of the control of Vegas. When you mix things down to a stereo file, there is nothing that is in that rendering that will explicity stream on any given systems LFE channel.
