Re: Audio issue on SDR Console

Ken Sejkora

Hi Nick,


No, I’m using the onboard (motherboard) graphics adapter. It’s an Intel HD Graphics 630 chip on an ASRock B250M Pro 4 motherboard.  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 24%, and when ‘idle’ without SDRC the CPU load is about 19%.  The CPU indicator at the bottom of the SDRC screen show CPU utilization at about 2.8%.


I don’t run any games, so the only other things I might do while running SDRC is checking email, doing some internet surfing with Chrome, and at times running some ham radio decoding programs (fldigi, MultiPSK, etc.)

Ken, do you happen to have a Nvidia graphics card?

The reason I ask is that I have had intermittent problems routing audio from SDRConsole to a WDM driver for a media playback software. I don't get these problems routing audio from any other app (including SDRUno and SDR++). The snap, crackle, pop stops happening completely when I start a GPU intensive game while running SDRConsole. As soon as I exit the game, the pops begin again. I've tried changing settings, like disabling power saving settings in Windows and Nvidia control panel; nothing helps. Just wondering if you have an Nvidia card. If not, I don't want to hijack this thread and steer the conversation in a different direction. I'll start a different thread at some point.
