Can I have speaker and spdif on at the same time, it was doing this

It has stopped doing it.
Last night after figuring out the spdif sound pass thru for the TV, I was able to hear same sound out of HDMI and the PC speakers, but this morning NO, it is only one or the other.

I could not get it to do it again. But I did find voicemeter does output same audio with no delay so no echo at all, to 2 playback devices.Install it, run program, set A1 to spdif, A2 to speakers, playbacks same sound to both at same time.
If you close voicemeter, sound turns off, so it has to b running and set to default for playback.

So its solved but not like it was working before, which was a win10 fluke, but since it had been working, win10 could do it by itself somehow.

Easiest way to autostart at boot, put a shortcut to voicemeter in the win10 startup folder, winkey+r, then type shell:startup to open folder.
