Re: VAC/audio problems on 200D

Hi All, When you run VAC1(VAC2) with the RingBuffer Manual checkboxes unchecked (in the Buffer Latency group), here is what happens: PortAudio goes out to your sound driver and asks it to report the minimum latency it is capable of doing. Thetis gets that info from PortAudio and then tells the Chann...

Hi Neoklis,

You may have better luck with that question over in the OpenHPSDR reflector.

Re: VAC update (muzychenko)

I've always wondered if V.A.C. re-clocked the audio streams passing through it. So now I guess we know :)

I wonder if they are re-threaded also?

Re: New 7000/8000 Orion MKII Protocol 2 Firmware Topic

I can confirm that the DHCP packet loss anomaly is now gone :-)
Thank you Rick!

Everything else seems to be about the same as pre4. Maybe the seq errors are a bit lower, but time will tell.

Yep, that's the signature we're looking for!

Also, patterns like:

and
0 0 0 3 -3 0 -3 3 0

Those are the sorts of things the PRO can put back into order, like it never happened.

That's correct!
