Sound from one speaker... Not a problem, a tip only

I was having problems with sound only coming from one speaker on the laptop. This was running Bullseye on a Dell G5S Ryzen7, there were seemingly no problems except sound only from one speaker, even when you did the test audio left and right within the sound setup, no matter how many changes made, or times the laptop had been restarted.

Turns out when the balance was adjusted just once, and then reset back to centre everything has come right. Sound from both speakers and starts up every time perfectly now. I thought i'd chuck this post up quickly in the case it might help someone.
