Find Audio settings in the IPTV app (Smarters/TiviMate usually have Audio or Player audio options).

Fix 3 — Change TV/soundbar audio output settings

Easy 3 minutes
Samsung TV LG TV Any HDMI setup
Open TV audio output settings

Go to TV Settings → Sound → Digital Output / Expert Settings.

Set digital output to PCM for testing

PCM is the most universally supported output.

If using AVR/soundbar, test passthrough

If PCM fixes it but you want surround, set TV to passthrough and let the soundbar/AVR decode.

Fixes by Device

Start by switching audio tracks and testing an external player. Then force PCM output for compatibility.

Disable Dolby passthrough in the IPTV app, set TV output to PCM, and test with VLC.

Toggle passthrough and confirm your sound system supports AC3/EAC3. If unsure, use PCM/stereo.

Check TV audio output: PCM is best for troubleshooting. If using a soundbar, test passthrough vs PCM.

Use VLC and test audio device output in Windows. Update audio drivers if system audio is unstable.
