Multi-channel crashes

Using a Macbook Air M1…Under DAC input, when I set it to 7.1 (I have an exaSound e38 DAC) in order to listen to multi-channel DSD, when I initiate play, AS immediately crashes. This happens regardless of the file type I attempt to play (i.e. 2 channel FLAC or multi-channel DSD). If I set the toggle “Use as Stereo only” to on, everything plays fine.
