Cannot be used in Expression Encoder with built-in speakers

[tompbsmith]

I am using this software to record system audio using the Expression Encoder SDK for C#.

My problem is that if I try and create a LiveJob using the "virtual-audio-capturer" as an EncoderDevice it works great if headphones or external speakers are plugged in (into 3.5mm jack on laptop) but if I try and do so with no external speakers/headphones, Expression sees "virtual-audio-capturer" as an audio device but if I try and start recording with it I get a run-time error:

"SystemErrorException: Cannot create device. The device may be in use by another program."

Is this a known problem? I am having trouble understanding why this error occurs or if there are ways I can try and troubleshoot it.

I am using Windows 8.1.

Thanks.

So if headphones are not plugged in then it doesn't work?

Yes that's the case, sorry if I didn't make that clear in my post.

When headphones/external speakers/anything like that is plugged into the 3.5mm jack it works perfectly but if not it seems to think "The device may be in use by another program.".

Interesting [yeah, this only "works" if there is an audio output device is
can basically receive input from] what if you install a virtual audio
device like http://vb-audio.pagesperso-orange.fr/Cable/ ? [sorry I'll be
AFK for the rest of this week/weekend so may not respond...]

Okay I'll have a go at doing that and see what happens. Maybe there is just something messed up with the driver with my built-in speakers. I'll try on another machine and report back as well as installing that virtual audio device.

I tweaked it a bit, care to try again?
