[PROBLEM] Multiroom Audio - Receiver Volume Control Not Working

[Tim Curtis]

Try the following commands on the sender Pi.

This command dumps the variables related to the receiver host names and ip addresses.

Code:

sudo moodeutl -d | grep rx

Example:

pi@moode:~ $ sudo moodeutl -d | grep rx
multiroom_rx|Off
rxactive|0
rx_adv_toggle|Advanced (+)
rx_hostnames|pb1, sig
rx_addresses|192.168.1.138 192.168.1.219
upd_rx_adv_toggle|Advanced (−)

Select one of the IP addresses from the above command output and use it in the URL's below to send commands to the reveiver. Paste these URL's into your Browser. 

The -rx command should return a status line to the Browser.
The -set-mpdvol should set the receiver volume to 10

Code:

http://IP_ADDRESS_OF_RECEIVER/command/?cmd=trx-status.php -rx
http://IP_ADDRESS_OF_RECEIVER/command/?cmd=trx-status.php -set-mpdvol 10
