I am writing a simple capture program using 0.9.8 and a PDAudioCF card.
I want to recover gracefully when the A/D converter stops and starts
sending signal during capture. When signal is lost, I call
snd_pcm_start periodically until the signal returns and continue
capture. On odd numbered starts (first, third, fifth stop/start of A/D
converter) everything recovers normally and I continue to capture the
output of the converter. However, on even numbered starts (second,
fourth, sixth stop/start of A/D converter) I capture full scale white
noise.
I'm probably not doing something right. Any pointers or suggestions
will be greatly appreciated.
thanks,
burris
