I updated the firmware manually, replaced the SD card, and
the music library loads just fine. I select some music, or just
press “PLAY”, and the music plays for about two minutes.
Then it starts humming, and keeps right on humming, until I
shut it off. No music - just humming, buzzing, whatever you
want to call it <it’s not static hiss>.
Has anyone experienced this? And is there a fix?
