Moving on from the SMB 1 issue itself, decided to go back to a previous configuration where I loaded a copy of my iTunes Music subfolder onto a spare drive on a Desktop PC (on 24x7 for media management). The iTunes Library itself is stored (now) on a Synology NAS.
BACKROUND - 7 device system, ethernet connected, been doing SONOS over 12 years
I had this working for a couple of years until about 4 months ago when the drive I was using was tight on space, so I removed the Music Library and played with the SMB1 issue on a prior NAS. Proud it worked; but onto today.
I installed another drive in this PC, it it Drive A:
I tried to add the specific copy of the iTunes music subfolder using this file name:
A:\O Drive\iTunes\iTunes Libraries\iTunes Media\Music
NO GOOD "computer name" not responding
Since I had already seen the SONOS app accept the simple “A:\” for the library, I then tried:
A:\O Drive\iTunes\iTunes Libraries\iTunes Media
NO GOOD "computer name" not responding
OK SONOS, how about this one???
A:\O Drive\iTunes\iTunes Libraries\
OK Library being added (took a while, lots more media there), but it got added
SMB-1 turned off on the Host PC, SONOS app is playing fine.. and from another PC, no SMB-1 needed
EXPLANATIONS?
