📺 TV audio format is not set to PCM

If the Audio Signal is FLASHING WHITE, the TV may be sending an unsupported audio format such as Dolby or DTS.

Set the TV's digital audio output to PCM.

🦻 Hearing aids are connected to the phone but not the broadcast

Being connected to the phone does not necessarily mean the hearing aids are connected to the Audikast 4 Auracast broadcast.

Find a broadcast → Audikast 4

🔄 Audikast 4 is in the wrong mode

For hearing aids, the transmitter must be in Hearing Aid Mode.

● SOLID WHITE = Hearing Aid Mode is active.

Tap the Auracast button ONCE to switch to Hearing Aid Mode.

🎧 Headphones are connected to another device

Bluetooth headphones or earbuds may automatically reconnect to a phone, tablet, or another nearby device. Turn off Bluetooth on nearby devices and reconnect the headphones to the Audikast 4.

📱 Another audio stream is using the hearing aids

Hearing aids may connect to the phone for calls, music, notifications, or other audio and interrupt the TV broadcast. Make sure the hearing aids are not actively streaming audio from another device.

💡 Important Tip for Hearing Aid Users

If your hearing aids connect but the TV audio cuts out or does not play, turn Bluetooth OFF on your phone after the hearing aids have connected to the Audikast 4 broadcast. This can prevent the phone from automatically reconnecting and interrupting the broadcast.
