Just because you've asked the audio sink to set a rate of 48k, doesn't mean the rest of the flow-graph agrees with that decision. It also doesn't necessarily mean that the audio hardware supports a 48k rate (although, most do).On Sat, Sep 6, 2014 at 4:13 PM, Marcus D.

Looks like I am running too much on that laptop and will have to move to another machine.Or your flow-graph isn't properly constructed to send samples to the audio subsystem at the right rate.Well, I have the sample rate set to 48k.
If you're getting audio *overrun* (as opposed to under-run), it generally means that you're sending samples to the hardware faster than they
can actually be processed by the hardware. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
