Hi.
The situation I'm describing was already happening in a Raspberry 3b+ before. Now I've moved to a Raspberry 4 and the same thing happens: when I try to play videos or music, on an external drive, it fails. Sometimes, rebooting will solve the issue, only momentarily.
I've uploaded the full log here: http://ix.io/25vz This is a fairly new install, with no "irregular" addons, AFAIK.
Can anyone help me here, please?
Thanks and best regards, Luís
