no powersaving involved

Not using a USB audio device? If you are, you need to check: https://www.pcworld.com/article/3045567 ... dtime.html

Nope, not using one - and the one I have is air-gapped. not plugged in.

And I note just now that this same problem afflicts playing previews in effects - but as before only after returning to Audacity and only for first use.

I don't see the problem on Linux, so perhaps it's specific to Windows.
Does the choice of "host" (in the Device Toolbar) make any difference?

Nope, same with all three hosts.

Try testing with an older version of Audacity. I assume this issue is relatively new, but it could be due to changes in Windows rather than changes in Audacity.

I get the same with 2.2.2

On further testing (on Linux), I notice there is a delay when first playing after changing the selection, but the delay is only about half a second, not 2 seconds.

On my w10 HP Envy SSD I can now reproduce this more simply

1) Import some audio
2) Ctr+2 for normal zoom
3) set cursor at 2 secs
4) press Play (usually plays but sometimes get 2 seconds of silence)
5) Press Stop befor waveform needs to reapint
6) wait 15+ seconds
7) Press play
8) Obsreve: Audacity plays 2-4 seconds as silence the adio trips in at 4 seconds

It's the 15 seconds that's critical - below that the Play starts properly at 2 seconds


BUT testing on my new HP Probook SSD - I can't make this happen - nor can I get it to happen on Mac - which suggests it nmay be a problem with my HP Envy PC rather than a problem with Audacity.

But I've never noticed this before, ever and I've been using this PC for a fair while now. And note that I've been getting Windows updates from Microsoft recently - so I'm not willing to rule that out as the culprit.

Peter

I've had a good look at my Sound settings and I can't seem to see anything there that would affect or cause this - no delay, no buffering

the audio was a 1h20m show I recorder last night

That's probably just about big enough for RAM to play a significant role.

But recently I've been testing with 3 and 5 minute stereo songs - And I still het this on the HP Envy

Peter

And today I can't reproduce this on the older HP Envy either
