Avidemux out of sync

[mylesaway]

I am not computer literate so my problem might be obvious.  But I can't really do anything complicated to fix it.  Just warning you!

I have a Mac Mini.  I recently got Sonoma 14.5 OS.
I am currently running Avidemux 2.7.1

I didn't really have this issue on an earlier OS but now audio seems to be consistently out of sync with the video outputs.

When I check the Shift box and type in 300 or 200 and then output the video again it seems to fix the audio sync issue.  However, this is an extra step and I am wondering if I am missing something obvious.  Like, do I download and use a later Avidemux?

My concern is that in the past when I have gone to a later version on my computer or iPhone, the app doesn't work!

What should I do if anything?
Thanks,
Mylesawy

I am currently running Avidemux 2.7.1

Is "7" as version minor a typo? If you are running the 2.8.1 release, I would not expect that the latest 2.8.2 nightly build behaves differently regarding audio device latency (and it is just a guesstimated hardcoded value), but anything older than 2.8.1 is entirely unsupported.

I'll recheck audio sync on my MacMini. Didn't notice anything unusual in this regard running native Avidemux builds. However, a hardcoded latency doesn't look reassuring.

It is not a typo.  I am running 2.7.1

If I upgrade, will Avidemux run on my mac mini running Sonoma 14.5?

I am speechless.

If I upgrade, will Avidemux run on my mac mini running Sonoma 14.5?

Please make a backup of ~/.avidemux6 directory (or rather rename to ~/.avidemux6-ancient), then try the latest nightly (it is x86_64, so it runs via emulation on an arm64 "Apple Silicon" MacMini). If it doesn't run, we'll look for a solution.
