Dazz.
this ezcap is also a video device ..correct ??
frankly i would be surprised if it was a rb problem.
with respect there is no way you can assume just cos audacity works
etc etc..and immediately come to the conclusion that it must be an rb problem.
ive seen people useing various daws , includeing friends junk their particular daw
software , and upon close inspection i often found it wasnt the daw
causeing the problem but many times how the persons pc was set up
and/or how things were set up in the daw software itself.

from a software engineering aspect whether Rb or sonar or cubase or
any other daw software they all work the same way.
let me elaborate mate.
basically all daws in their start up go thru a routine asking windows for the audio n midi devices
on a users pc. dont matter daw software used.
so a driver table is instantiated. and this is how drivers are displayed in each daw
for user selection. there is even a common programmers api for this in windows.
the term is "device enumeration".

basically the application daws...are divorced from the sound device itself.
windows sits tween the sound device and the daw application itself.
think of it like this. in laymans terms irrespective of daw.
imagine a bridge tween two mountains.
on one mountain sits the daw software , and on the other the sound device.
with windows being the bridge that spans the two mountains.
so heres what happens...
the daw says "hey windows mate...what sound devices does this pc have ??"
window says ..lol.."hold on mate i'll tell ya"...n trots off n looks on
the other mountain to see how many sound devices are living on the other mountain.
lets call it sound device village on the other mountain.
so lickety split win sends out a scout to look at the devices in sound device village.
then says back to the daw software "hey i got these sound devices".
and thats the basics of it mate.
in summary its not like a husband n wife cuddled up at night in bed.
its more like hubby in one hotel room and wifey in another hotel room
and a mediator going tween each room.

now ive explained the process, where some people get caught is they often
dont have audio preferences etc etc set up properly in the daw software they use.
so the best bet is to post a pic of your audio preferences in RB...
and this might help people help you.

i frankly wouldnt use ezcap with a daw.
i would use a proper well known sound interface mate like many users do.
i looked up the device but had probs finding detailed info.
for example no audio output jacks. less i'm mistaken.
this brings me to a point.
in windows control panel sound itself youll prolly need to specify that
your recording device is the ezcap BUT...playback is useing on board sound.
have you done that ??
please tell me in windows sound properties what are the selected
devices for recording and playback.
