How to stop audio input latency from suddenly increasing out of nowhere?

Hello everyone, I am new to Studio One. I own Studio One Artist 5.1.2 since the 09/02/2021.

I am experiencing a rather buffling issue with the audio latency.

I am using ZOOM H and F ASIO driver, but also ASIO4ALL v2 at times (It happens also with the other drivers) and with Device Block Size set to 512 samples (Not the top for recording, but it is pretty latency-free on my system, almost imperceptible).

The problem here is that after about 10-15 minutes the audio input latency starts to slowly increase to the point that it sounds like I'm using a 1/4 delay as vocal effect (which is not the case).

And by leaving it there more time (even without touching the computer), the overall audio quality slowly decreases to the point of sounding gritty and more and more noise is added to it.

This happens without me adding or removing any effects (I have only the stock EQ and the stock REVERB). As matter of experiment I have tried to leave the computer for that amount of time to see if it was something I was doing that was causing it, but it would still happen.

The first thought I had was that the block size was too high, but it is just enough for me to open the Audio Setup shown in the image and click again on the same 512 samples for this to be solved. Problem is that within 10 - 15 minutes it happens again.

I have tried to reduce the block size to 256 and lower, but the problem still persist. I have also tried to use the "Input low latency monitoring", but it does not get any better.

I can already confirm that it is not the computer, and I doubt it is the ASIO driver either, this because I also have FL Studio on my laptop and it does not give me this sort of issues. If a delay is present it is usually caused by a plugin, and it is enough to disable such plugin for things to carry on smoothly.

Can anyone please help?

It is a very frustrating way to begin my transition to Studio One.

Hey mate hope you are well.

There is an ever increasing number of us who have this known issue but obviously not enough for presonus to actually do something about it.

Did you get a reply or work it out, or just the old presonus company line of deny deny then lie?

Hey ya, unfortunately it seems that ignoring paying users is a normal thing around here.

If anyone knows a solution

I run into this exact same issue periodically, only when I am using Studio one 4.

Hi, I use SO4 and I also have this issue. After 5-10 of tracking gtr, the latency increases without me adding any plugs or doing anything differently. If I restart SO the latency is good but then comes back after 5-10min.... very weird

Anyone have a solution??

never put a bx_masterdesk on your master bus, removed it and issue solved. "user-too-stupid" error this time, not sure if this helps anyone. Or you read this and facepalm as hard as I did :D

Middle of 2022 and here we go again.

Recording a song with 5 tracks and 2 virtual instruments and my latency suddenly increased to at least 30ms even with lowest possible buffer size of 16 samples. S1 shows a latency of around 3ms which matches the buffer size quite well but reality just looks different. Using a presonus studio1824c interface on my highend-ish studio machine.

Restarting S1 doesn't change a thing and in a different project everything is fine (with 60 tracks and 5 Kontakt instruments), issue seems to persist with one project somehow.

Any idea welcome...
