Hi Derek, Thanks for the response. The answer to your question "Do you have a throttle block or a piece of hardware?" is that I used USRP N200 hardware to get data. I also placed throttle block as well. I checked on different possible sample rate of sound card. The problem is whenever I run the same program on 8 core CPU, it works fine. I changed the motherboard as well. It is working fine with 8 core processor on any motherboard; but create choppy sound on 12 core processor.
