gettting Unhandled WAV chunk on scan

I just moved from windows to linux (Centos 6.8).

I started LMS manually and while rescanning, my terminal session reported many messages of the type:

Unhandled WAV chunk UITS size 1108 (skipped)
Unhandled WAV chunk bext size 858 (skipped)
Unhandled WAV chunk DMC size 16 (skipped)
Unhandled WAV chunk cart size 2048 (skipped)


Are these an issue?

Thanks,

Peter
