With REW 5.19 32-bit, I can get Generator to work for whichever speaker I try first, and I can stop and start the output just fine. But if I change the speaker selection, I no longer get any sound output until I restart REW. With REW 5.20 RC11 32-bit and 64-bit, it's similar but worse, in that once I stop the Generator I no longer get any sound output, even if I don't change the speaker selection. Windows 10 20H2, AISO4ALL 2.15 Beta 2, Intel Display Audio. Any suggestions?
