Library update issues - Leviathan - 12-05-2020
Would welcome any help in resolving my issue.
Running a very simple set up - FLAC files stored on a USB stick, plugged into one of the USB 2 ports on my Pi4.
Issue is whenever I remove the USB stick to add more more music, I don't seem to be able to "remount" the USB stick so that all music is visible in the Library.
Latest example - today. Ripped CD to FLAC and copied to USB stick. Re inserted stick into the Pi and then tried both "update library" and then, Config/Library/Music database/Regenerate.
The new album does not appear under "Artists" or "Albums by Artists".
However, I know it's on the USB stick because if I navigate to Library/Folder/USB and then dig down through the file structure, I can both see and play the album.
I'm obviously doing something fundamentally wrong and would welcome any help.
Thanks

Very odd.
In tag view does the Genre or Artist named "Unknown" appear?
RE: Library update issues - Leviathan - 12-05-2020
Hi Tim.
Looking at the screen now.
Under both Genre and Artist, I have "Unknown"
Under Genre, "unknown" lists several albums under "Albums by Artist". However, none of these are the album I copied today.
Under Artist, "unknown" lists just one album.
I am clearly doing something very wrong!

Try clearing the Library tag cache
Menu, Configure, Library
Also examine the MPD log to see if there are any errors related to the files.
cat /var/log/mpd/log

Thanks, Tim.
I did clear the Library tag cache earlier.
Will have a look at the MPD log.
In simple terms - and I do get very easily lost when trying to undertstand tags, etc - why do some albums end up under "unknown"? Is the answer simple or complicated?
Also, will an album stored under "unknown" still play if Moode/Pi is set to random play?
Thanks

Yes it should play.
Unknown means that particular tag is missing from the file.

Thank you Tim. Much appreciated.

@Leviathan
Your ripper did apply at least a basic set of metadata values to the tracks in a Vorbis Comment tag, yes?
You can use the mediainfo utility from the command line to check the values. For example, here's the first stanza of the output for the Stereo Test file:
Code:
pi@moode3a:/mnt/SDCARD/Stereo Test $ mediainfo LRMonoPhase4.flac

PS - sometimes ripper/tagger apps mix up ID3v2 and Vorbis Comment tags on FLAC files. There should be only the latter. Easy test---use the file utility from the command line. Example:
Code:
pi@moode3a:/mnt/SDCARD/Stereo Test $ file LRMonoPhase4.flac
LRMonoPhase4.flac: FLAC audio bitstream data, 16 bit, stereo, 48 kHz, 1860560 samplesIf that 4-character string "FLAC" doesn't appear at the beginning of the line for a FLAC file, then it's likely an ID3v2 tag has been added to the file whether a Vorbis Comment tag is also present or not. This is incorrect usage and can cause confusion.
ETA: PPS - I'm using "tag" in the strict sense of the container of the metadata key/value pairs and not in the sense of individual metadata key names.
