Hey @smathijs
Welkom op de Sonos community!
Sonos S1 is niet langer compatible vanaf DSM versie 7.1.1-42962 Update 5.
Deze ga je dus op een manier moeten terugzetten om het nog te kunnen laten werken met Sonos. Hiervoor moet ik je helaas refereren naar de Support van Synology.
Hi, I finally found it! The problem was that I must have missed something while implementing a suggested solution from a forum. Today I tried it again and everything seems to work again. The solution was to do the following: update etc/samba/sbm.conf with the line únix extensions=no. Then I needed to lower the security level by enabling NTLMv1 authentication (file services/SBM/advance/other).
I found all info here: https://en.community.sonos.com/components-and-architectural-228999/access-denied-to-synolog-nas-server-can-t-play-files-in-one-room-other-rooms-are-fine-6882384
Thank you for your reaction but luckily I was able to fix it.
Regards,
Sander.
Ik dacht gezien te hebben dat mijn vraag was vertaald naar het Engels. Dus vandaar
