However, I'm not seeing these MusicBrainz messages.
I suggest try disabling MusicBrainz and see if that helps.
(Plenty of other providers of Album Covers).
I have disabled it in Settings → Covers → Cover providers, but I'm still
getting the same results. I am pretty sure Strawberry uses MusicBrainz
as a CD metadata (album name, song name, artist) provider as well, and I
haven't been able to locate an option to disable that.
Also, I would suggest raising an issue upstream here;
https://forum.strawberrymusicplayer.org/category/5/technical-help
I noticed that there are upstream builds for Debian 13 (Testing), which
are installable on Unstable, and I am able to reproduce the issue there,
so I'll just report this on GitHub (for now, I'll put this in the report
I linked, since it seems to be the same issue).
I have also tried reproducing this on a different machine with Debian 12
(Stable), and I've gathered that the Debian package for 1.0.14-1 works,
upstream builds up to and including 1.0.23 work as well, but upstream
builds of 1.1.0-rc1 and up don't - that said, these print out the
"MusicBrainz discid" line once, and the drive doesn't sound like it's
seeking. Interestingly, no upstream builds, including 1.0.23, seem to
work on my primary machine with Unstable, and they always have the same
output as the Debian package.
