Hello, I use a Synology ds214play NAS running MinimSever, an RPi installed in an Okto Research dac8 Stereo running upmpdcli, and a BT Smart Hub 2, with audio files stored on an SSD in the NAS. My preferred control point is LUMIN, but which I use does not appear to be part of my problem. The problem occurred after moving home. Previously, there were no issues. I had a gap in Internet service, and my original BT Smart Hub 2 failed and was replaced before I got everything set up again. All IP addresses appear correct, and auto DHCP IPAddress is set up. With the help of manufacturers/developers, I know the audio files are sent to the RPi, but they do not play. The connection between the RPi and dac8 also appears to be fine. Would anyone be able to guess where the problem lies, or could help with instructions to try and locate the problem? I only have basic knowledge of such matters, so any help would be greatly appreciated. Thanks!
