Why do IPTV channels show “audio not supported” on some devices?
This happens when a device cannot decode certain codecs like AC3, EAC3, AAC+ or Dolby formats. Older Smart TVs and low-end boxes often lack licensing support. Use a player that includes built-in audio libraries, switch audio tracks, or use external decoding. Providers optimized on Glanfy typically standardize audio to avoid compatibility issues.
