Hi Sara - Can you give us something more to work with, for example a link to the Youtube video and another to your code? I'm sure folks here can help, but without more info the best we can offer is high-level suggestions on how to fix sample rate differences. - MLD

I'm using a USRP205mini-i. I followed the YouTube tutorial online on how to build a FM receiver. I execute the flow graph, and all I hear is very choppy and high pitched audio coming from my computer's speaker (i see aUaUaU and an occasional O. I know this has to to with the input/output frequency being to fast/slow). I can make out the radio station I'm tuned in, but not very clearly. When listening to the .wav file produced, it sounds perfectly normal. I did change the audio sink sample rate to 48kHz and the wave file sink to 68kHz instead of keeping it at the original in the tutorial. Any suggestions or ideas as to how to fix this?
