Doesn't stay active in Windows 10 r1803 #35

Windows seems to realize that SPDIF-KA isn't actually outputting any audio and removes it from the list of applications that are outputting audio after a few minutes (either that, or something is closing the audio stream and SPDIF-KA doesn't realize it). If I stop-and-start SPDIF-KA it shows up again, but until then it doesn't do anything to prevent my soundbar from going to sleep.

I'm using it with the HDMI out on my Nvidia GPU in case that's relevant. I get the same result regardless of whether SPDIF-KA is set to "Inaudible sound" or "Silence".

Same issue on 19628 using optical digital out.

Sound Keeper is a similar program, but it supports more signal types. You can try a low frequency sine, it should help in your case.

@vrubleg well bloody awesome, thanks for that - works perfectly (and i had never solved the issue!) Running with default options seems to be perfect for use with my SoundBlaster DD encoding sound card.

Random question, windows system volume control doesn't work when using encoding cards, have you ever seen a tool to 'workaround' that?

vrubleg commented 2 years ago

If you are not talking about exclusive mode, it sounds like a driver issue. I would try to contact support of your sound card about this.

thanks, its a windows issue :-( due to change in audio subsystem IIRC it last worked in windows 8 (or maybe it was vista) and changed in windows 10

and in a grand demonstration of synchronicity this was created recently!!! and does what i need https://github.com/nicojeske/MasterVolumeSync

keeps volume of master volume and DD output device in sync image

vrubleg commented 2 years ago

Still sounds like the driver wasn't updated for the new OS and works a bit incorrectly.

it is definitely a windows subsystem issue - i worked at MS when some bright spark made the dumb decision to change how the windows audio subsystem worked. I agree, creative (realtek chip folks) should be embarrassed they never figured this out in the last 12+ years....
