Hi Multi,
In 0.3 Samba was on by default, in 0.4 you need to enable and start Samba (once with systemctl)
You are right samba seems to be disabled by mistake.
systemctl restart smbd
systemctl enable smbd
Restarts and enables samba, so that it will be available even after reboot.
Question about Webradio is solved.
I modified the Samba configuration.
Great to hear that you have solved the problem.
Maybe others also like to know how you did this!
You have to add this
[MusicStoreWebradio]
comment = MPD MusicStore (/mnt/MPD/Webradio)
path = /mnt/MPD/Webradio
read only = no
public = yes
follow symlinks = yes
wide links = yes
to /etc/samba/smb.conf and reboot or restart samba.
