Audikast - Fix No Sound

No sound usually means the headphones aren’t connected, the TV audio format isn’t set to PCM, or cables (OPT/AUX) aren’t securely plugged in.

Quick Check

1️⃣ Check Transmitter Signal & TV Audio

● OPT/AUX solid blue → TV audio detected

● OPT/AUX flashing blue → no audio detected from TV

Quick fix: Re-check the TV audio output and cable connections, then set TV Audio Settings → Digital Audio Output → PCM. Learn Here

2️⃣ Check Headphone Connection

● Solid blue → Connected to transmitter

● Flashing blue → Not connected

Quick fix: Pair the headphones with the transmitter. Learn Here

💡 Tip: After TV updates, audio settings may change automatically. If sound stops working suddenly, recheck that PCM is selected.

Most Common Issue

●Headphones not fully paired (transmitter not solid blue)

●TV or source not sending audio (flashing white indicator)

●Volume is too low or muted on TV/headphones

●Some TVs need digital/optical output set to PCM, not Dolby

Still not working?

● Try a different cable or input type (AUX or optical)
