Am I missing something, or is it not possible to select the audio input device (NOT the input channel) from within capture mode in VirtualDub? It allows you to select the video capture device, but not the audio capture device.
I can switch devices by changing the default device for the entire system in the "Sounds and Media" control panel and then restarting VirtualDub, but this is a pain.
If it matters, I need to switch between an onboard "SoundMax" sampler, and a SoundBlaster Live! sampler. (Running VirtualDub 1.4.10 and Windows 2000)
Thanks!

I guess that's the way to go

I am not completely sure, but there should be a way to define a kind of 'priority' in Windows for both, such maing the preferred one your default audio capture device ?
I cant test because i dont have any installed here on this machine ....

I configured my system like this...
1. sound from my capture device to line In of my sound card
2. sound from my VCR to mic In of my sound card
when I open up VD (capture AVI) and select the video source then I can choose with my windows sound control panel which sound to capture... either I turn on/ off line In or turn on/ off mic In. When choosing mic In make sure your VCR has turned on the same channel as you want to capture. Otherwise you will capture BBC as source but recieve sound from CNN 
That's because my captured sound using line In will result less clear but without annoying cracks/ breaks (german word: Knackser - I don't really know it in english) on the other hand using mic In via VCR will result in clear and crispy sound but on high voices (someone is crying) I'll recieve the mentioned cracks/ breaks...
that would mean to you that you'll only have to do one or two clicks either click on lineIn or micIn - that's not really a pain...

Hi
Nothing specially liked to VDub but :
The annoying cracks you're having and the general difference of quality between Mic In & Line In are due to the fact that those two inputs are designed to receive different types of signals.
Line In expects a signal already amplified, while Mic In has an integrated amplifier (that cause your sound bugs).
In general, you should plug things like TV, VCR, HiFi hardware or music instruments on Line IN and onmy Mics on Mic In. |

thanks dude,
that's the way I get used to for a long time but since I got my ATI-RadeonAIW I have to live with crappy capture driver support. That means, the sound I'll recieve from my AIW plugged in LineIn always goes up and down. ATI knows this soundproblem with (all?) AIW and although they have crappy driver support, they update their capturedriver nearly every month... that speaks for itself.
Beside of that I recognized sync-problems whenever I take LineOut (VCR) to LineIn (soundcard) but I won't recognize them if I plug in the sound to micIn... but then I have the mentioned sound breaks 
Even VD_sync can't solve my problem when I stick to your proposed way to configue my system.
cheers Sill

The Windows AVICap library is hardcoded to use the wave mapper's default audio input device. I have a workaround that allows audio device selection from code, but it's rather ugly: patch the in-memory DLL import vector for waveInOpen() in AVICAP32.DLL through a stub in VirtualDub. I haven't verified yet if it works in Windows XP. (It does work in 98 and 2000, as that is how the hardware YUV preview acceleration works.)
As for the audio input issue, there is another reason not to use the microphone input besides distortion: it's mono-only.
