Hi Simon,

 

Thanks for the ideas.  Just for baseline information, the CPU is an Intel Core i7 7700K running at 4400 MHz.    I have 32 GB of DDR4 RAM running at 1200 MHz.  When running SDRConsole, the total CPU load is around 22-24%, and when ‘idle’ without SDRC the CPU load is about 17-19%.  The CPU indicator at the bottom of the SDRC screen show CPU utilization at about 2.8%.  A screenshot of the CPU load is attached. 

 

How do I find the logfile for the session?  Where is it located?  Do I actually have to ‘create’ it while running SDRC, or is it created automatically?  Do you want a logfile with SDRC running while on VAC, and another while it is sending output directly to the speakers?  Once I know how and where to get it, I’ll send it to you.

 

Thanks again.  --  Ken

Also,

 

What is the general CPU load on your computer?

Ken,

 

A few ideas:

 

• SDR Console uses WASAPI, the other programs the WDM audio drivers.
• If the audio is OK via speakers but not over a VAC then it must be the VAC causing the problem, specifically the drivers.
• Please show the logfile for a session with the VAC – I want to check a few things.
