Step 2: Check if there is valid audio signal being fed into the Audikast.

- If connected using TV DIGITAL AUDIO OUT(OPTICAL),

- If connected using TV RCA ports,

1) ONLY use the Red/White ports LABELED  “AUDIO OUT”. Other RCA ports are usually AUDIO IN and incorrect. Plug wired ear buds into the TV RCA ports with 3.5mm AUX to RCA audio cable, check if you can hear sound. 

2) Change your TV audio OUT setting to "External Speakers".
