I recently panned everything to the left and nothing was coming out, as if I muted the channel.
This was not the case when I unplugged the headphones and the speaker was emitting the sounds like normal.
I tried this on two different gameboys and the same thing happened.
ssSSooo I'm assuming this is a software issue?
I'll re-flash it once I get the chance.
Reasoning why I'm posting this is to see if this has happened to anyone else.
It's possible the one side on your headphones crapped out, actually. test them with something else, like your laptop.
weird..
When I said headphones earlier I meant to say my tape adapter for my car, and that was giving me issues.
Couple days earlier I had awful sound issues that were also lead me to believe of panning issues.
Yet, they work with my actual headphones...
I guess that venue's sound system blew/and or the sound guy hated me.
I feel really silly now.
Or perhaps the cord/stereo is only using one stereo channel, check to see if the cord you're using is stereo.
If it was plugged to a mixer who has 2 inputs for stereosound, then you should use a twinheaded cord. Stereo cables - at least in my experience - don't work with mixers if they use only one input. Using mono cords solves my problem but I don't use panning.
tape adapter is probably fucked. get a new one.
