No audio from left headphone

[Android Central Question]

Hi, trying to find a fix or workaround for an g4 that only gives audio from the right side from the 3.5mm jack
have tried:

- checking accessibility settings to stereo / balance etc
- checked multiple headphones
- replaced headphone port (really hoping that would've solved it..)

any other ideas?
possible workaround for stereo sound? bluetooth headphones? (but charging headphones is not what I want...)
is there usb to headphone jack that actually works on a g4?
any advice much appreciated
thanks
