Some get API functions are not supported by my HT-CT800

Question

My Device from getInterfaceInformation

{
    "id": 33,
    "result": [
        {
            "interfaceVersion": "4.0.0",
            "modelName": "HT-CT800",
            "productCategory": "homeTheaterSystem",
            "productName": "Bar",
            "serverName": ""
        }
    ]
}

Firmware version is M39.R.0377

I tried use getSoundSettings with

{
    "method": "getSoundSettings",
    "id": 73,
    "params": [
        {
            "target": ""
        }
    ],
    "version": "1.1"
}

and it returns

{
    "error": [
        12,
        "getSoundSettings"
    ],
    "id": 73
}

also use getSupportedApiInfo still return

{
    "error": [
        12,
        "getSupportedApiInfo"
    ],
    "id": 5
}

These methods work:

• getInterfaceInformation (v1.0)
• getPowerStatus (v1.1)
• getSWUpdateInfo (v1.0)
• getSystemInformation (v1.4)

Make sure you are using the correct path http://{{IP}}:{{port}}/sony/{{lib}} for the method you are calling for "getSoundSettings" it should be http://{{IP}}:{{port}}/sony/audio and for "getSupportedApiInfo" it should be http://{{IP}}:{{port}}/sony/guide.

You find the lib for each method listed in the API reference https://developer.sony.com/develop/audio-control-api/api-references/api-overview-2
