Left output is quieter than the right one

[nhandt64]

I started a new session of work and fire up my favorite song but easyeffects generate the left output noticeable quieter than the right output. I tried to restart pipewire (and related services/sockets like pipewire-pulse, pipewire-media-session - as user) but it still happens the same. All of preset and irs files are untouched.

Another thing is if I turn off the program in Players tab, the sound is still normal (in flat). This is clearly easyeffects' fault.

My distro of use is Arch Linux, uses KDE Plasma as the Desktop Environment. The headphones and speakers sound the same issue.

Here's the output of G_MESSAGES_DEBUG=easyeffects easyeffects, I saw nothing goes wrong except some GTK symbol is unable to be loaded:

the left output noticeable quieter than the right output

An image of one of the plugins window showing the input and output level meters would help. What happens if no plugin is enabled? Is there still difference in the channels level?

Another thing is if I turn off the program in Players tab, the sound is still normal (in flat)

I did not understand the problem. If you disable the app switch we will not process it. The app will play directly to the sound card.

I am start to think that something unusual may be happening when easyeffects is executed in KDE. In pulseeffects early days we also had a fair amount of problems that only happened in KDE. I wonder what it is the cause now.

It's kinda late here but I think before I started that session, I removed a number of packages. Do you remember any missing packages that possibly cause the issues? I will try them in tomorrow morning. Thanks for your reply!

Unless there is a bug I am not aware of those missing packages warnings in your log should not be a problem. Those plugins should be optional. I also do not see how a missing package could cause a difference in channels volume. The reason for that is probably more subtle.

When you have time run pw-dot and attach the file here on github. I will use xdot to view it and check if you are having missing links between ports like other people on KDE seem to have.

An image of one of the plugins window showing the input and output level meters would help.

Here it is, I have not noticed about it before 😅

Here's the output of pw-dot (Github does not allow me to upload the file in .dot) pw.txt

I had successfully address the error from your first reply (which I didn't think about). It was not EasyEffects' fault.

When I was trying xfce, it also installed pavucontrol and I believe it caused EasyEffects' sink unbalanced like below.

Sorry for any inconvenience I made to you.
