Hello, I’ve found a really unexpensive solution. I have an unused Lacinema mini HD, and it provides DLNA ! So it cost me 0$ :).
It’s compatible but I have no volume control, and i can’t pause music or forward a song. I can only play and stop music, but i just want an arlam clock so it’s ok for me.
I just bought the NAS ALARM CLOCK license, and I’m happy 🙂
