Hello,

I could simulate what you said and it's very strange. But once I removed the below marked portion it worked as expected. I created a project from scratch like your exact project and it worked as expected (not adding the below part).

I will look into this and will get back to you.

Regards,

Harish

Hello again,

I have tried few things here.

I did a small change and made it work as expected. It's strange but I need to analyze what's behind it.

In your delay0 block, you used 32736 samples and once I reduced that to 32735, it worked as expected.

1) So, for now, please use 32735 (DM1) samples in delay0 and 8185 (DM0) in delay1, 8184 (DM0) in delay2 and 4096 (DM0) in delay3. In this way you will have the same delay samples as before and the project will work as expected.

Please look at the screenshot below.

2) And as I previously mentioned, deleting that logical part makes the project work as expected. You can keep the delay 32736 in delay0 here. I know it doesn't make any sense in your project without including your logical part yet I'm just saying what I tried.

You can use the first solution for now.

Both the readback shows the audio level between -1 and 1 (0dBFS).

Regards,

Harish
