Choppy audio
Needs Information from User, NormalPublic

Description

Blender Version
2.93 LTS

Short description of error

Ever since I installed 2.93, for some reason the audio is being really choppy even if I set the playback to "Sync to Audio"
At first I thought it was the video itself, but after digging deeper, it turns out its the blender version itself.

Exact steps for others to reproduce the error
Switch to 2.93
add an audio into the video sequencer
switch to "Sync to Audio"

Notice how the audio becomes choppy even in the fastest viewport. Not sure if its just my pc, but this never happened in 2.92

I am not able to reproduce this with 2.93.0 LTS. If this is happening for a specific file then please attach .blend file with the report.

The issue happens in any file, no point of sending one.

It also seems like I am not the only one with this type of problem by looking at the latest bug reports

@Anoca (Maker26) Please fill in the missing information in your bugreport about your system information. Are you using Linux? Then this might be a duplicate of T88507. Otherwise this one T88875 or this on T88815 could be the same issue, although it's hard to tell just yet. Definitly try if a different sound API like OpenAL fixes the issue.

I'm using windows 10 with the latest Intel Core i3-7100

The audio device was set to Wasapi as default
Changing to OpenAL solves the sound issue for me

EDIT: Correction, SDL fixed it better

What happens, when you try WASAPI with a bigger mixing buffer size? Does it work better then?

tested it and yes, the audio gets better on a higher mixing buffer size while using WASAPI

Great! Seems like our default is too low for your system. What is the lowest value that works fine?
