Firmware 21 is released to support Spotify Lossless to all Lumin streamer models.
To use Spotify Lossless:
- Make sure you are subscribed to the (paid) Spotify Premium
- Wait for Spotify to notify you that you are entitled to Lossless quality playback
- Make sure your phone is on WiFi and Lumin is powered on and connected to the network
- Update Spotify app to the latest
- Update Lumin firmware to 21 or newer using Lumin app
- If you have disabled Spotify Connect in Lumin app before, please enable it in Lumin app
- Launch Spotify app, (top left hand corner) profile → Settings and privacy → Media quality → change your (phone speaker) Audio Streaming Quality to Lossless
- Play something that is NOT what you usually play using your phone speaker, make sure you see Lossless indication on the track
- Switch the output to Lumin
- (The playing track becomes 320k quality)
- Change quality settings → Lossless, confirm to “Turn on lossless”
- (The current playing track remains to be 320k even after the quality setting has been changed)
- Play a different track so that this new track is Lossless
- Repeat the steps for changing quality setting for every piece of hardware, because the quality setting is per device rather than global
- Settings > Data saving and offline (scroll down to the end) > Clear cache
The strangeness of this procedure comes from the per-device setting, and I experienced an issue that previously cached 320k track remains to be 320k even after I changed the quality to Lossless and changed tracks multiple times.
