I can successfully get and render audio through the native server using one of the example layouts, but when I create a new layout, I cannot get the new layout to interact with the server. Any clues as to what I'm doing wrong? I'm running 6.17.06 on a Win7 machine.
What is the source of your audio? Is it a file, or are you using line-input (like a microphone)? This is controlled for your layout in the Layout->Layout-Properties menu in Designer.
To make sure that audio is getting into your layout, place a meter in your design and click Run to see the signal on all the available channels. This will help show whether the problem is with your input or with your output.
Also, make sure that your audio input/output configuration is correct in the Server (File->Preferences).
Hopefully this helps, but if you still have problems, please respond with additional detail on what you are doing and what you expect to hear or see.
I figured it out...I guess if you are using the real time IO, there needs to be a driver sink as well as source. I was trying to do some simple real time filtering with some metering and spectral display and only had a source input from the native server. Can you confirm that? If there is somewhere in the docs that mention this, a pointer to that would be helpful also.
I see the same result when I test without a SYS_out pin. Currently, the system requires that there is both a HW input and output pin in order to pass audio, but the system build does not fail if the input or output is missing (hence your confusion). I've put in a ticket to fail the system build if the HW output pin is missing from the layout and to report a helpful message.
Thanks for pointing out this gap!
