I have just downloaded MusicBee.  It has scanned my music folders (very large - around 500GB via a RAID array attached to a Win10 PC) and seems to have done a good job indexing, pulling cover art, etc.  However, when I go to play something I get one of two errors:

Unable to open file (error=BASS_ERROR_CODEC) - happens to .mp3 files

Unable to play this file - it has an unsupported format or is corrupted - this is common with .m4a files

I am able to play both on other players, so am pretty sure it's not a formatting or corruption issue.  I can't find any way to diagnose more deeply or figure out if settings need to be changed.  I downloaded this as it is well reviewed, but if I can't make it work, I'll need to find another program.  Any suggestions for resolution appreciated.

Hi, welcome to the forum!

I'm not sure about the mp3s, because they should work out of the box, but for the m4a files there's a codec you need to download.  You can find a link in the FAQ.

the same for mp3s, but only for N-versions of windows (some european versions)
