Nexus 6 Some sounds/ which speakers do what

Hello, i have a Nexus 6. All was working well, i had small update yesterday(i was already on android 7) and next time i went to use my phone, i had no sound when making phone calls, unless i put it on speaker phone. It also rings normally, but has no sound when playing back youtube or audio files. Headphone jack works fine. I tried reset, still nothing. Im not afraid to replace speakers, but im not sure they are bad, because when it rings i get sound from both. Any ideas?
