DLNA server FLAC playback issues

RouterOS RouterOS beta
1

Hello MikroTik community,

I’m testing the DLNA server feature on hAP ax3 with RouterOS 7.20beta6. The new FLAC extension support is a welcome addition!

Here are my observations so far:

  • The very first FLAC file copied directly to the USB disk (not via SMB) plays correctly on DLNA clients (Wiim, VLC, TCL TV).
  • Other FLAC files are visible in the DLNA media index, but fail to play (Wiim shows “Cannot play”, VLC sometimes fails too).
  • FLAC files copied via SMB share are sometimes not indexed or not visible in the DLNA media library until a manual DLNA server restart.

Possible issues:

  • DLNA HTTP responses for FLAC files may be missing the correct Content-Type header (audio/flac or audio/x-flac).
  • DLNA server may not handle HTTP GET requests for FLAC files properly.
  • Media indexing may not reliably detect new files added via SMB without a restart.

Test environment:

  • Device: hAP ax3
  • RouterOS: 7.20beta6
  • USB disk formatted as ext4
  • DLNA server configured under /IP media
  • Clients: Wiim Pro Plus, VLC on PC, TCL Smart TV

Would love to see these issues addressed to make DLNA fully usable for lossless music collections.

Thanks for your efforts and looking forward to improvements!
