Re: Do you have ASIO working with any digital programs like FLDigi, WSJT-X, or JTDX?

I have ASIO working with both SSB and digital modes . I'd echo what Scott has written , voicemeeter is a great solution.

Re: How to solve latency problems and VAC under/overflows in Windows 10

Thanks for the fix. I can confirm that Thetis actually works better now on my system with lower ring buffers than previously.

Re: VAC under/overflows due to changes in how Windows handles Timer resolution

I have implemented Jordi's (EA3AQR) fix and audio now looks very solid on Windows 20H2. Many thanks to Jordi for coming up with this solution.

Re: VAC under/overflows due to changes in how Windows handles Timer resolution

Thanks for the info Bryan, seems its not a widespread problem Hi All, Thetis' VAC1 & VAC2 use the PortAudio library to do all its IO to the sound hardware drivers. I subscribe to the PortAudio mail reflector and scan or read all the messages that come across. I have seen zero chatter about this ...

You are right of course , I am back to 1909 which was installed on 14/10/2019 but it seems the roll back to this did not revert fully as I still have the problem. This is W10 v.1909. I don't remember if V.1909 is also afected by this issue, for sure v.1903 (13362) isn't. Edit: I may have misspoken R...
