silence when I reboot into High Sierra

Have the same problem on a 2010 white plastic macbook running high sierra.

Nothing I found on line worked. Then one day I booted it from a Linux Ubuntu install USB stick and the sound worked fine all the whie that OS was booted so mine is not a hardware problem.

It went back to silence when I rebooted into High Sierra. Does that tell anyone here what needs to be fixed on mine? thanks djc

Chime always worked but no sounds afterward.

Lets clarify things your issue is not the startup chime, its your lack of sound after boot (no music, podcasts or videos) is that correct??
