Hi. I'm currently using the Wiim Ultra and the Wiim Sub Pro together. I'm an Android user and currently use Power Amp (mp3), YouTube Music, Tidal, and Melon (a Korean streaming app). After using various music players, I noticed that the Wiim Sub Pro doesn't work at all when streaming via Chromecast with YouTube Music or Power Amp. Tidal works fine. Melon allows me to choose between Chromecast streaming and DNLA, but when I select Chromecast streaming, the Sub Pro doesn't work. When I run YouTube Music within the Wiim Home app, the Sub Pro works fine. When I play MP3s stored on my smartphone within the Wiim Home app, the Sub Pro also works fine. All experiments were performed with the same song. It appears to be a problem with Chromecast streaming. Does anyone have the same problem as me?
