I assume you have tried a few of the basics
- Disable all streaming services in Roon
- Disable all folder locations in Roon. Do you have any setup?
- remove SMB path in Sonictransporter. The path to your NAS should be setup in Roon
- Add a few albums to an Exfat formatted USB drive and mount the USB in Sonictransporter. Then in Roon under storage, Sonic transporter, drill down to the USB folder and point it to the new folder you have your music stored in on the USB Drive. Click “Add”
- Clear Roon server cache and restart Roon server in sonictransporter
- turn off all filters and upsampling.
- Connect everything via ethernet directly to your router, transporter, endpoint, NAS
- Unistall and reinstall Roon. This won’t delete your playlists and database
- Do a complete fresh install of Roon, this will delete everything:
Accessing the Roon Database on your sonicTransporter
Long and short, try to get one thing running seamlessly first. Then add in other pieces after you have it stabilized for at least a full 24 hours straight
