[PROBLEM] 2 moOde systems, same config, same music source, different songs counts

[zazouboy]

By how much do the song counts differ?

You can try the command below to see what MPD thinks.

Code:

mpc stats

Both count 501 albums.
One shows 7477 tracks, 499 hours, 58 mins
mpc stats
Artists:   1463
Albums:     511
Songs:     7477

The other one 7021 tracks, 467 hours, 41 mins
mpc stats
Artists:   1463
Albums:     498
Songs:     7021

Even weirder !

I also compared both "System Information" outputs, I have the exact same information regarding the music database regeneration :

Also do you know why sometimes I have this message : "Zend media exception: Not a valid FLAC bitstream" and sometimes no message at all for the same track ?
Maybe I should test with the SSD drive directly attached to Raspberry Pi ?

Have a good night !
