### Frequently Asked Questions
#### How to fix shadowtv free iptv no audio on samsung qled with hdmi arc?
Disable Anynet+ (HDMI-CEC), set audio output to PCM in the IPTV player, and ensure the HDMI cable is HDMI 1.4 or better. Then restart the TV first, then the player.
#### Why does shadowtv audio work on one channel but not others?
The channel’s audio stream may be encoded in Dolby Digital or DTS. Switch your player’s audio output to PCM to force compatibility.
#### Can I use optical out instead of HDMI ARC?
Yes—but only if your Samsung QLED has an optical output (many Q60C/Q70B do). In **Settings > Sound > Headphone/Audio Out**, choose **Optical Digital Audio Out**, then set your soundbar to “TV Speaker” mode. PCM is required.
#### Why does sound cut out during live sports on shadowtv?
Live sports use high-bitrate video and audio. Reduce buffering: lower resolution to 720p in your IPTV player, enable “hardware acceleration”, and use a 5GHz Wi-Fi or Ethernet connection.
#### How do I know if my Samsung QLED supports eARC?
Look for an **ARC or eARC** label on HDMI 2 (usually). Q80B (2020+) and all Q90C/Q95C models support eARC. If unsure, go to **Settings > Sound > HDMI eARC** — if the menu appears, your TV supports it.
