I'm using LV 2011 and Si Read hangs after about 5 min. I am using Si Config: 8Khz/8Bit/Mono/240 Samples, and Si Start outside a while loop. Inside the loops is now nothing but Si Read. The vi freezes after 5 min everytime. Seriously, that's what I've honed it down to. Just that.
Is replacing the lvsound functions with lvsound2 an option? Something like:
Another alternative is WaveIO which is an 3rd party sound API for LabVIEW. I've found it to be slightly more reliable than lvsound2 in terms of buffer issues and audio glitches.
