Audio cuts out for short period when beginning shuttling in v25.6.2

​@Adolfo H.  Appreciate the insight. I think then there might actually be a bug in the intended fade/ramp you describe.

I used Audacity to generate a constant sine wave file to be able to more exactly see the times involved. As you can see the fade/ramp in fact only lasts about 5 milliseconds, the rest of the gap is silence and lasts exactly 123 ms every time, on my system at least.

(There also seems to be some kind of almost-zero audio for 42ms after the 5ms fade out, and and for 5ms before the 5ms fade-in, not sure that’s relevant.)

So basically it fades out over exactly 5 milliseconds, has a huge 123ms gap of silence (which is the obtrusive part), and then fades back in over 5ms again. As opposed to a ramp that lasts 100ms which I assume is what was intended (which seems rather long in the first place, I'd imagine even 5ms ramp would be sufficient, without the huge gap of course).

And to be clear I didn't stop and start playback here, the gap occurred when I was playing the video normally, and then pressed the shuttle key once to make it play faster.

Additional Troubleshooting:

The timeline FPS doesn’t seem to make a difference. I tested it on a 59.94 fps timeline and a 1000fps timeline, and it’s the same 5ms ramp and 123ms silent gap. I also tested changing the device sample rate from 48 KHz to 44.1 KHz which made no difference in the gap or ramp time.

However I did notice a difference when I changed the “Latency” value in the Audio Hardware settings (I am using Windows MME). Setting the latency to 30ms it became a 111ms gap of silence. At 500ms it is a 158 ms gap. Same 5ms ramp for both. So it could be related to how the ramp and delayed speed change interact with Windows’ audio buffers.

Also for what it’s worth, I never really experienced the pop when shuttling before. And like I mentioned, I personally think a 100ms ramp (assuming it were working as intended) is unnecessarily long. Probably only a few milliseconds would be sufficient.
