A custom, real-time Linux music-server & player image that bundles Lyrion and Volumio on a PREEMPT_RT kernel for x86-64 PCs/NUCs/MAC (Intel).

If you're looking for a way to turn your computer into a music player with a familiar desktop interface — where you can hit play on YouTube Music, watch music videos or browse news websites while listening to music from Lyrion (connected to your hard drive or NAS), and enjoy many built-in features like Roon Server, HQPlayer, UPnP, and more — you've just found it. AudioOS with a Desktop GUI.*

• Real-time audio core
  PREEMPT_RT 6.12.17 tuned by the Lyrion SQ patch-set → lower latency, less jitter, cleaner sound.

• Personal music library manager
  Scan and play files from internal SSD/HDD or household NAS (CIFS / NFS).

• Next-gen audio transports
  Diretta Host, AoE Vsound Netmap for bit-perfect, low-CPU LAN streaming.

• Universal web control
  Open http://<your-PC-IP>:9000 on any phone, tablet or desktop → Material Skin UI.
