Hi Joel,

I think I might have an answer for you if you're still working through your issue. I have my ISD1700 and PIC recording and playing. I also had the same issue where it appears to stop working. One of the things I realized is that if I send a record command or play command that blinks the LED, if I send a read status without the fourth bit enabled for the LED, the LED will not come on or blink for the record and play respectively. So I realized that the chip was still recording although the LED wasn't playing. Any new command you send should set the fourth bit to keep the LED working.

How's the programming coming for you?
