The following Just Add Power devices have analog mic- and line-input ports:
The analog audio input ports are able to embed an audio signal onto the HDMI signal, transmit that across the network to a Receiver, and have the Receiver play the audio signals. This leaves the possibility for 3 audio signals - HDMI, Mic-input, Line-input - to be combined.
No Analog Audio on TX and RX
The Mic-Input and Line-Input ports are not enabled by default. Enabling the ports must be done manually:
|Enable Mic-In||dd_mic_on.sh||Enables the Mic-In port|
|dd_mic_mute.sh||Disables the Mic-In port|
|Enable Line-In||dd_line_on.sh||Enables the Line-In port|
|dd_line_mute.sh||Disables the Line-In port|
|Enable HDMI Audio
|dd_main_on.sh||Enables the audio signal coming from the HDMI source|
|Disable HDMI Audio||dd_main_mute.sh||Disables the audio signal coming from the HDMI source|
Analog Audio on TX, No Analog Audio on RX
Once the Mic-Input and Line-Input ports are enabled, audio will play out of the Stereo port on the Transmitter. If the audio signal is not playing on Receiver - through either HDMI or the Stereo port - that means the HDMI signal does not have audio and the audio driver has been disabled on the Transmitter.
To enable the audio driver on the Transmitter all the time - regardless of if there is HDMI audio or not - send this command to the Transmitter:
astparam s v_rx_drv_option 6;astparam save;sleep 1;reboot
The Transmitter will reboot once the command is applied. WARNING: This setting will cause the Transmitter to always output a signal. Do NOTrun JADConfig with this setting applied on a Transmitter.
If using 2G devices - or 3G devices in 2G Mode - the audio driver on the Receiver also needs to be enabled. Send this command to the Receiver:
astparam s a_force_dual_output y;astparam save;sleep 1;reboot
The Receiver will reboot once the command is applied.
