Re: Audio issue on SDR Console

Valid question, Dale. I looked at what else was running in the background, and when I shut down MalwareBytes, CPU load dropped from ~18% down to about 7%. Wow, I never would have guessed a running anti-malware program would consume that much processor power.
I also run a outside temperature logging program using rtl_tcp in the background to monitor a separate RTL-SDR looking for the remote temperature sensor signals. Those temperature readings are logged into a text CSV file. If I disable all of those processes, (text logging, rtl_tcp, etc.) the CPU load drops from 7% down to around 3%.
I’ll try running SDRC with all of these other background processes disabled to see if it makes any difference in the audio popping. For what it’s worth, I’ve been running those background processes for the past couple of years without any issues, and they never seemed to cause any issues. As mentioned in the original email, I first noticed the popping arising after installing a Microsoft features update. I don’t know if that’s just coincidence, or if some aspect of the update is causing the problem.
Thanks for the insights. Have a great weekend, Dale.

Hi Ken. I am wondering why "when ‘idle’ without SDRC the CPU load is about 17-19%". Something is utilizing about 15%. I have an I7 @ 3.6G and it is at 2-3% most of the time and up to about 7% on peaks.
