Greetings,

?

I am using the latest version of FLDigi on my Win 10 desktop.

?

I was trying to select one of my Virtual Audio Cables and I get the message shown on the attached picture.

?

I have Restarted the computer and the message persists.

?

How can I clear this error and select the input that I want?

?

I have attached the screen capture and the VAC Control Panel.

?

I would appreciate any help with this issue.

?

Thanks,

I meant to say, that clearing the message leaves Port audio grayed out. except for its radio button.? Clicking on it yields the error message once again.

Hi George,

I am not sure that this will help, but please try the following 2 items.


In your VAC control panel, set the minimum supported sample rate to a really low value, this shouldn't hurt and maybe FLdigi tries to use 8000 or so at least in some cases.

From the very beginning, I have even set it to 2000 (= 0...1000 Hz audio, an unusually low value which I hardly ever use for signal processing), but even this low limit value was accepted and has never caused an issue.


On the other hand, I can also reproduce the error message in certain cases, and then it's just a question of trying to click and select a device you know to work ok, e.g. microphone input, and attemt clicking just fast enough before the error occurs. This is a bit iffy at times, in Windows at least, but my proven 'debug sequence' is as follows:

0. PortAudio is unchecked following an error message.

1. Click to activate PortAudio.

2. Immediately thereafter (!!!) click on the 'Capture' list (if this is the one causing the issue).

3. The 'not available' error message pops up (never mind).

4. Close the error message.

5. If you were fast enough, you should now have the device selection list visible where you can select a working device.

6. PortAudio is still unchecked.

7. Click to activate PortAudio.

8. PortAudio is selected (checked) and fully available again, and so is the device selection list.


I hope this will work for your problem as well. Tested here on fldigi ver4.2.06.19 and Win7.


Good Luck!

Your Port Audio playback device is the same as your audio alerts. I would start by disabling audio alerts. Maybe then you can activate Port Audio and fix the playback device.

Thanks to all. After a few tries I was quick enough to get to the list. I did find a post from a few years ago about editing one of the xml files, but the method in this thread worked.?

?

Of course this brings up the question why were 12 of my 15 VACs ok, but as it turned out 3 weren't. There was no other software that used audio running when this situation happened.

?

Again thanks,

George?
