Openshot skips/fast forward playing preview

Linux Mint 20.1 Cinnamon user here.

I just upgraded my PC from an Asrock z97m pro 4 mobo +4790k CPU to a ryzen 5900x and Asrock x570 taichi mobo (current BIOS p3.40 which is dated August 2020)

All I did was just plug in my Intel 750 800GB pciexpress ssd (LM20.1 was installed into it already) into the new build got all booted fine.

Problem is in Openshot 2.5.1 when trying to play back a video clip…it now does this stupid auto -sound skipping/fast as well as the video playing itself is auto fast forwarded too.

This never happened with my older build.

So I’m think either it could be any of or combo of the following:

  1. The realtek ALC 1220 Audio just won’t place nice with Open shot …( ***note. I have to manually set the sound output source in VLC media player to Alsa to ensure movie playback audio didn’t skip or lag since this upgrade also) in LM20.1 Cinnamon…+++ I have yet to test my new build in Win 10 pro 64 using Open shot to see if it’s Linux mint’s built into-kernel sound driver that us the problem involving my Realtek Alc 1220 sound chip set…

  2. Maybe this version or any version of Openshot doesn’t like my audio chip set versus the Intel one I had on that aseock z97m pro 4 micro axt mobo.

  3. Perhaps it’s the fact that Openshot is trying to use an audio chip set that isn’t there anymore and I should just install LM20.1 Cinnamon…fresh start given its different audio hardware I’m dealing with now.

I also tried Kernel 5.4.whatever, 5.8.whatever,both stock via Linux Mint’s update Manager, and 5.10.17 via Ubuntu mainline updater . still same problem.

I’ll upload my inxi terminal command results and any other command results needed when I get back home in a few hours.

I basically, temporarily- enough, solved the problem. I decided to see if other or older versions of Openshot would show the same problem. 2.4.3 so far does not and everything just works as it should.

Sucks I cannot try to leverage gpu encoding, but whatever (Shrugs). I’m a complete noob to editing videos so there may be something I’m missing here.

It’s just odd that with my older build, 2.5.1 and 2.5.0 Openshot versions didn’t give me this bs problem where as with my new build I’m having to revert back to an older Openshot version to have positive results.

*** Update 3-7-21 ***

I tried the 2.5.1 appimage version found here OpenShot Video Editor | Download … and it works like a champ…

note

I’m unsure about any versions between 2.4.whatever and 2.5.0 or 2.5.1…but with 2.5.0 an onward to get the most out of your system and/or cpu, set the OMP threads to 20 and the ffmpeg threads setting to 16.
