Thanks for your comments, both Laurie and Bill. I am quite satisfied that one of the power settings available in Win 10 Control Panel is not the problem. I have scoured (several times) every device I can find that has a power setting and made sure that nothing gets turned off.
That is not to say that there might be something else peculiar about what Win 10 is doing. Also, I have opened the control panel (which gets installed with the driver and which always has an icon sitting in the system tray) for my USB audio card almost immediately after experiencing the problem with WSJT-X and watched the input VU meter bouncing just above its lowest level, meaning that, it was seeing the output of my radio. That tells me that the USB port has not been shut down by the system. Bill, I understand your hesitance add a recovery feature for audio cards, but such a feature might be similar to the way some OS's display a notification that a network cable has been unplugged. As soon as you plug the network cable in again, the OS recovers gracefully and even grabs a new dynamic IP address if necessary with no further user intervention. Seems pretty simple from a user's standpoint, though I don’t know how difficult it might be to code in WSJT-X. I also understand your hesitance because only Mike and I have reported this problem, as far as I know. But there may be folks experiencing it without commenting. 73 Dave HS0ZLG WA0PND ---------------------------------------------------------------------- Message: 1 Date: Tue, 29 Sep 2015 11:46:35 +1000 From: "Laurie, VK3AMA" <vk3ama.ham.a...@gmail.com> Subject: Re: [wsjt-devel] Decoding stopped To: WSJT software development <wsjt-devel@lists.sourceforge.net> Message-ID: <5609ed7b.30...@vkdxer.com> Content-Type: text/plain; charset="windows-1252" Dave, This suggests that you still have your USB port going to sleep. You need to check the Power Management settings of the USB soundcard and also the Power Management settings of the USP Root Hub to which the soundcard is connected. de Laurie VK3AMA -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 2 Date: Tue, 29 Sep 2015 09:58:36 +0100 From: Bill Somerville <g4...@classdesign.com> Subject: Re: [wsjt-devel] Decoding stopped To: wsjt-devel@lists.sourceforge.net Message-ID: <560a52bc.2040...@classdesign.com> Content-Type: text/plain; charset=windows-1252; format=flowed On 29/09/2015 02:18, Dave Halbakken wrote: Hi Dave, > Thanks for your reply, Mike. > > I found that this problem can be reproduced by unplugging and re-plugging > the USB cable to my soundcard.

The symptoms you have described are best explained by a USB audio device disappearing for some reason. The most likely cause of that is some operating system driven partial shut down in my experience. I know you have checked that the USB hub sleep settings have been disabled but I do not know the full details of the Windows 10 changes in that area. > > But that brings up a feature request: please make recovery from the > temporary disconnection of a soundcard both graceful and automatic if > possible. That is not straightforward. Maintaining a setting of a USB audio device that has been removed from the system is leaving the application with an invalid configuration. Currently we do support USB audio devices being removed while the application is not running; so long as they are restored before the application is restarted. IMHO supporting non-existent devices will lead to far more user issues than the current arrangement. Running WSJT-X for extended periods of time while the system is liable to initiate a power saving strategy, cannot be supported unless that power saving strategy does not impact the resources being used by WSJT-X. > > 73 > > Dave HS0ZLG WA0PND 73 Bill G4WJS. ------------------------------------------------------------------------------ _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
