I'd disable APO or any other audio effects/eq applications first. Then check if the outputs (hardware) are fine or not. Check in sound settings too, the sound device properties, make sure to disable all effects.

Those pc/laptop headphone outs should just work as long as the driver is installed. It's something they figured years ago...

The "symptoms" like i describe like hearing 50hz mostly on the right side, happen even with out APO installed so the APO is not the reason why it happens. I don't use any audio effect. Just plug and play. The hardwares are fine. I tested all the dacs and iem in my possession with my phone, it doesn't have that imbalance. So yeah. It's makes me kinda crazy right now, not knowing what's the reason for this

You must be very lucky. If it's still in warranty, I'd have that replaced/fixed. If not, just use a dac.

If your dac connected to pc still has the same problem, then that is software issue. Maybe there is still some effects/eq running somewhere.

I use a dac (7hz 71, Faaeal KT4099, Jcally JA03) as well as just the 3.5mm female jack, it's all the same. So yeah, i think it's software issue. I mean, i manage to balance out the channel with APO turn on so it's definitely software related. I just don't know which ones
