I've never seen this happening on my computers. Unless that for some weird reason you cpu is not being able to keep up with the additional load the only possibility is the media player you are using not working right with virtual sinks. In any case I doubt there is anything we can do from EasyEffects side. Sounds more like some issue between the player and PipeWire.

What is in the output of pw-top when this happens?

It happens consistently in all video players. Here is pw-top directly after it happened: Screenshot from 2024-05-29 09-42-09

It is not perfectly reproducible, happening every time. But it has never happened with EasyEffects not running.

But it has never happened with EasyEffects not running.

Is there any change if you remove all the filters from the pipeline? But if it does then the only explanation would be the cpu not being able to handle the load. What is odd considering the model.

There isn't a way for EasyEffects to mess with the video playback. It just moves the player's audio stream to a virtual sink and process what is present in the virtual sink monitor ports. For all the players to be affected something unusual may be happening in PipeWire that is messing with the players playback rate.

After further testing it only happens when my filters are active and not otherwise.

Here is the preset I use: cab-fw.json

Hum... If passthrough is ok then the additional cpu load is somehow doing it... Very strange...

I tested it here on my computer but at least on Firefox and mpv I could not see anything unusual.

The issue seems to have disappeared.

The issue seems to have reappeared.

The issue seems to have reappeared.

Do you notice any unusual load on your cpu if you open your system monitor or a program like top or htop? Nothing changed in EasyEffects in this time window. If the problem came back there is something else in your system that is not always running that is interfering somehow. Or a system upgrade introduced a regression.

Really sorry for the long delay.

I’ve taken a picture of top and pw-top right when it happens. Screenshot from 2024-07-07 23-22-40 Screenshot from 2024-07-07 23-22-43
