While trying out some WebSDR it seems that I couldn't get any SDR to produce any audio. I looked into a previously reported SDR of the University of Twente at forum topic 28898, and I couldn't get that to work either, tuned at 6150 khz AM. I looked into previous versions via fresh portables, and it looks like the issue started in 34.2.2 (it works in a fresh portable of 34.1.0, 34.2.0 and 34.2.1). Probably a regression caused by the DiD for audio channel mixing?
