I have used HiFiBerry OS for some years now with the AMP+ which had worked well, but has over the last few months becoming annoying as it drops connection to Spotify as a device. The RPi3 is wired Etherent on the office network and can always be seen as a device, but Spotify loses the player. If I wait 30-40 seconds it will appear again in as a device and I can connect and resume playback.
I have this week finally got another system setup in the garage, which is another RPi 3 with DAC+ running through a Cyrus Amp to a pair of Yamaha speakers, sounds great, for about 10 minutes, then drops connection as a Spotify device. This also is wired Ethernet, over the weekend, it stayed connected for no more than 5-6 tracks, sometimes only managing 1 before pausing itself as it lost Spoity connection.
As both devices have the same issiue, I suspect a software problem. It is a real shame, as the HiFiBerry devices and OS have seemd great, but this issue is really getting me down and looking for alternatives
