Are you using simpleusb or usbradio for the channel?
Can you post your simpleusb.conf and simpleusb*_tune.conf for us to check out?
Cheers,
Rob
simpleusb.conf:

You can try to adjust rxondelay to 0 in simpleusb.conf and try that.
However, I’ve been working on some radio stuff today and I thought of your post. I was testing with my Clearnode (HamVoIP) and my ASL beta nodes and all have a very similar, pronounced delay that I wasn’t aware was so large. The delay varies, but I experienced them as long as 2 seconds. They’re all on the same network, connected through Ethernet.
This may just be normal behavior but it’s being observed by both of us for the first time. I’m not sure.
Let me know if the rxondelay helps!
Rob,
I think the delay has been there for a very long time for some.
And I’m sure you will find many that disagree with that.
While I have never set out to prove it, It has been my belief that is was a memory bandwidth issue with particular usb audio chips and the driver.
But that is just my opinion.
RXondelay, in theory, should have no effect on this.
