Realtek not able to play CbB sound - HP laptop

[Leizer]

On my working laptop (HP Elitebook), I have a CbB device setup with Focusrite 4i4 inputs and Realtek standard phones/speakers output (see pic).  When I plug in phones in my HP Elitebook I can hear the sound from CbB output. If I play without the phones to use laptop speakers playback stops and I get faulty message (see other pic). I there a way to "fix" this?

Or have I got this all wrong - that the Realtek speakers actually are lined out speakers from the phones jack or something, and not the internal HP speakers?

Are you saying this happens when you unplug the headphones? 

If so, perhaps the laptop's headphone jack has autodetect and when you pull the plug Windows tells software that the headphone output is no longer available which triggers the message that the output is no longer available to Cakewalk? If so, and your tracks are routed to the headphone ouput, do you get the sound back if you switch to a valid output?

Ahh, thanks! The CbB master output was set to "headphones". When I changed output to speakers it worked, of course.  Easy solution as always, you just have to think about it...
