I have the sam Issue SDR Console cutting RX audio. Also waterfall stops for a moment at the same time when audio stop. Interruptions are sometimes on few seconds some times disappear for a few minutes.
I am using Windows 7 on i5, 8GB RAM SDR Console V3..025 connected to Pluto with 0.32 firmware, also modifications made on Pluto GND R58-D3 and GND to 2x micro USB housing. Trying with USB and ETH. Via ETH is a little better.
I think the problem is on communications on relation Pluto PC. Did you find some solutions for this audio Issues.
