So recently guessing due to a windows 10 update Virtual audio lines became useless with sdr-console not sure what is causing it.
2 example videos

Hi,

I'm really not interested in videos from SDR# as I use the WASAPI drivers, showing me videos from other software just gets in the way.
  • Which VAC software are you using?
  • Have you looked for an update to the VAC software?
  • How is the normal playback?
  • Console is using ~2% CPU but the task manager shows 42%, what else are you using?
You really are running a very fast display rate, makes videos hard to watch. Try 20 or 40 lines/second.

i have tried both VB cable and Virtual Audio Cable (VAC) latest with VB cable it does take a while before problems occur thou
Normal playback is fine if i put to default
is my main pc so plenty of things running.

After the latest Win10 updates, the stuttering occurred. I use both: VBAudio-cable and also Vitual audio cable. The following remedied:
1. Complete deinstallation of the VAC software, PC restart
2. Download the latest software versions:

- VBCABLE_B_Driver_Pack43.zip
3. Reinstallation and then perform sound settings.

Hmm would not help in my case as i had not had VB cable before and downloaded latest and HIFI one worked a bit longer then normal but same issue occured soon.
Suspecting windows did another Fudge up similar to the DPC (Deferred Procedure Call) in update 1903(i think)

Don't blame Windows, blame the VAC.

so turns out old driver files were still present after uninstall and update removing them manually has fixed the problem i think at least seems to be working correctly for now.
but Thank you for suggestions
and thank you Simon for the great software :)
