[PD] vbap 1.0.3.2 crashes when sent longer "define_loudspeakers message"

[Hans-Christoph Steiner]

Sounds like you are the first to try it with that many speakers!  My guess is that something that allocates memory is hard-coded to a pretty short number.  I've used it a lot for 6 speakers and had no crashes.

Try changing this in vbap.h:
#define MAX_LS_AMOUNT 55
