You can't have a throttle block inline with an audio source. Did you try
putting the throttle between the file source and the selector?
(I haven't actually tried this)

Hi,
I'm using a flow graph with no GUI to demodulate a signal. I have a
selector block that allows me to select the source of the signal between
the audio card and a wav file. I can change the source using an xmlrpc
server/client.
If I don't use a throttle block with the wav file, the flow graph takes
all the CPU and the server/client is very slow.
If I put a throttle, I get audio underruns when using the audio card.
Same problem for a constant source.
Can anyone please recommend a better way to do this?
Cheers,
Murray
