JRiver 32 crashes when I play a 5.1 recording and switch to a stereo recording. The problem occurs when I use the source number of channels but not when I set the output to 5.1. It occurs with WASAPI but not Direct Sound. I am feeding the computer's HDMI output to a current-model Pioneer Elite receiver, which in turn feeds a Sony TV. I have two HDMI monitors, but the problem persisted when the other one was disconnected.
If I stop the 5.1 recording first, it's no problem; the stereo will then play. I have tried various things, like changing prebuffering and memory playback, sample rate output, to no avail. I followed the protocol to make sure Windows Defender was not the issue.
I have deleted and reinstalled JRiver several times. I am now using 32.0.28, 64-bit.
I attached a log file. I am not very computer savvy, so please be patient. Operating system is Windows 11.
