so i just connect my bloetooth speaker with my phone and it works perfectly, then i decided to connect it to my laptop. the sound is low, the 100% is same as the 50% from my phone connected to the speaker. once it works perfectly, which the sound is pretty loud, and the next day i connect it again, the sound is low again. i'm pretty sure that the main problem is from my laptop it self, I've been looking for the solution and nothing is working. any solution?
