Step 2: Check if there is valid audio signal being fed into the Audikast.
- If TV digital audio output is connected via OPTICAL:
1) Ensure your TV audio format is set to “PCM” or "DOLBY/DTS" is off, Bluetooth adapter does not decode Dolby/DTS;
2) Change your TV audio OUT setting to “External Speaker”.
- If connected TV via TV RCA ports:

2) Change your TV audio OUT setting to "External Speakers".
If connected using TV headphone jack,
1) Change your TV audio OUT setting to "Headset".
