Crackling and laggy behavior when capturing from easyeffects source/sink
EasyEffects Version
6.25
What package are you using?
Gentoo
Distribution
Gentoo
Describe the bug
When capturing from easyeffects source in obs as my microphone, frequent crackling will begin on my audio output, that may sometimes progress to downright unbearable screeching, this can be replicated with ffmpeg as well by using ffmpeg -f pulse -i easyeffects_source, or simply by opening pavucontrol. On top of this, capturing audio from easyeffects_sink, the only thing I could capture that is before the filter chain so as to not equalize recorded audio, results in very laggy audio in the recording that is not present when capturing my headphones device directly, which causes poor playback quality for me due to it being after the filter chain and being equalized twice, and undoubtedly impacts others playback experience as well as this equalizer is fine tuned for my headsets response curve. This happens regardless of whether I capture the device from pipewire or pulseaudio in obs, ffmpeg does not have a pipewire source, so no testing can be done there. The only filters I am making use of are the equalizer for my headphones and noise reduction for my microphone.
Expected Behavior
Capturing mic audio does not cause any crackling or screeching, capturing output audio does not result in a laggy recording, the screeching cannot be captured in recording for demonstration purpose unfortunately.
Debug Log
When adding this, my comment was too long, so I'm omitting some warnings about not installed plugins

this can be replicated with ffmpeg as well by using ffmpeg -f pulse -i easyeffects_source, or simply by opening pavucontrol.
Nothing unusual happened on my system. But there is something in your logs that may explain the noises you are hearing
soe: output_level: new PipeWire blocksize: 64
The blocksize is related the latency currently set by PipeWire. 64 is a very low latency that not every system is capable of handling. You may be having underflows https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Troubleshooting#underrununderflow-and-broken-pipe-errors.
You can verify if the too low latency is the problem by temporarily setting a higher value. Take a look at the quantum range section of https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PipeWire#quantum-ranges.
Yeah it seems the crackling issues with what I hear in the moment are definitely related to how low the buffer is, but it seems that the issue with recording is the inverse, the higher I set the quantum, when recording from easyeffects sink, the bigger the gaps in audio get for the recording, a constant oscillation between some sound and silence, no effect when recording from my headset no matter the quantum. Interestingly enough, removing the equalizer effect seems to get rid of the lag, which I figured wouldn't happen because helvum shows this as obs plugging into the sink before the filter, changing the mode between IIR and the others doesn't seem to have any effect on the lag either.
I have delved into a solution that works for my simple use case by making use of the base pipewire filter-chain config file which doesn't produce this issue, seeing as I have easyeffects no longer installed and cannot troubleshoot or give any more insight I'm going to close this
