Thanks for the tutorial. Although I did use VMB in the past I decided to use VAC with my new Anan 7000. I use Thetis v 1.9.
After a day or so of testing WSJT-x rc2 and after restarting my Windows 10 Home (most recent version) WSJT-X cannot find the VAC devices. I use a single cable and when looking at the VAC control panel I see that it is receiving audio from Anan 7000. When starting WSJT-X it reports "Error in Sound". The Thetis is fine with VAC1 when using WDM-KS, but NOT with MME.
I have done the microphone on setting in audio devices. VAC and WSJT-x have both been re-installed. VAC devices show as working in Windows and Thetis shows activity on VAC1..
Also tried to run FlDigi which also reports an error (Port Audio).
Short of re-installing Windows is there anything else that I am missing?

VAC Problem
Re: VAC Problem
Erik,
I split this topic off from the tutorial topic because it's not directly related to the tutorial and could turn into a lengthy problem-solving type topic specific to your situation.
The first suggestion is to upgrade to Thetis 2.6.9, the current release and available from the official TAPR openHPSDR Github repository. You might also consider further upgrading to the 2.7.0 beta, for that look to the 2.7.0 topic in the forum.
There should be two VAC cables instantiated, one to carry receiver audio from Thetis to WSJT-X or Fldigi, and a second to carry transmitter audio from WSJT-X or Fldigi back to Thetis. If you are only using a single cable that could be the cause of all of your errors.

Scott

Re: VAC Problem
Hi Scott,
I am using Thetis 2.6.9 and it WAS working with just the default VAC installation. Neither TX, nor RX works. I suspect a Windows update even though I have an update blocker installed. MSFT has a way of sneaking some updates through, anyway.
Under the VAC tab I can see activity in both directions, but no over or underflows, except for the first second or so after I enable VAC. Perhaps I will try VB-audio.
What I find puzzling is that VAC does not seem to do anything with MME. Perhaps there is a cue there? I am no expert on Windows.

Re: VAC Problem
UPDATE:....Solved.
I just uninstalled VAC and installed VB-audio. All is working now - with MME. QRV again with FT-8 and working DX.

There is nothing wrong with VAC and Windows updates on my pc (W10/64 PRO). I was running VAC 4.15 from 2015 up to know using Line 1 to Line 4 for wsjt-x, fldigi, Audacity, jtdx, spectrumlab.....
Last week I did update to VAC 4.62. But this gave me some strange occurences of eg. multible FT8 signals left and right from a strong FT8 signal. I than installed VAC 4.60 which solved the problem.
VAC is straight forward, just think of two or four cables between Thetis and any digital mode software. No switching, no mixing, no adjustments.
Edit: It turns out that I have a problem with the 4.6x versions of VAC!!!

My problem looks like the one mentioned in this tread viewtopic.php?f=13&t=3291#p9914
The pictures show what I have seen and I also could hear a crackling noise using the audio repeater. The problem with 4.6x was kind of intermittend, but I could not find a way to get it functioning stable.
I went back to VAC 4.15 which solved this for me. But I see very many overflows and underflows (see the picture) This is RX2 & VAC2 running a few hours on 144.174. Nevertheless, jtdx and wsjt-x seem to work fine! I did not change all of the settings to get that solved, but will try that tomorrow or later.
Maybe it's time to try banana or potato s/w

Re: VAC Problem
VAC 4.62 would not work for me after my PC updated to the Win10-64 2004 release. Going back to 4.60 works with 2004.
VAC 4.62 did work before the 2004 update and also works with Windows Media Player, VLC, WSJTx and FLdigi on 2004. Problem would seem to be with OpenHPSDR.
FWIW, a single VAC channel will work for both input and output with OpenHPSDR and FLdigi or WSJTx. However, I use two so that I can repeat the digi program input (radio out) to the PC's speakers with the Win10 "listen to recording device" function - separate channels also seems to give slightly less latency.

Oh, you are right. One vac line is bi-directional. I didn't know that. RTFM
