setAudioVolume "-N" not working on STR-DN860

root

I own a STR-DN860 (latest firmware - M29.R.0476 ) and I'm able to control the receiver's volume using setAudioVolume.
However decreasing by 1 isn't working.
I can set the "volume" parameter to any number and the volume changes to that number. Or I can set it to "+1" and it increases by 1.
However sending "-1" also increases the volume.

Does it work correctly for anybody?

We had what same result in earlier versions of the firmware for STR-DN1080 also, but I believe that is fixed for that receiver (don't have the possibility to test right now). Looks like the firmware for STR-DN860 is not updated since then (I don't know if the firmware will be updated for STR-DN860).

(edited) I specify an N value for the volume. Sure it means keeping track of the current volume, or you can (probably should) query that first. Not so handy if you are just wanting a simple script though.

@david It would be really great if Sony rolled out API updates to older models to tidy things up. Even if there are no other fixes, just the API updates.

@grolschie Yes, that's what I'm currently doing.
Here's my AutoHotKey 2 script, perhaps someone finds it useful.
It increases/decreases volume when middle mouse button is pressed together with volume up/down.

~Volume_Down & MButton::
~MButton & Volume_Down::
{
req := ComObject("WinHttp.WinHttpRequest.5.1")
req.Open("POST", "http://192.168.0.110:10000/sony/audio")
jsonbody := '{"method":"getVolumeInformation", "id":33, "params":[{}], "version":"1.1"}'
req.Send(jsonbody)
req.WaitForResponse()
currVol := Integer(RTrim(SubStr(req.responseText, 94, 2),"}"))
currVol--

whr := ComObject("WinHttp.WinHttpRequest.5.1")
whr.Open("POST", "http://192.168.0.110:10000/sony/audio")
whr.SetRequestHeader("Content-Type", "application/json")
voldown := '{ "method":"setAudioVolume", "id":98, "params":[{ "volume": "' . currVol . '"}], "version":"1.1" }'
whr.Send(voldown)

}

~Volume_Up & MButton::
~MButton & Volume_Up::
{
whr := ComObject("WinHttp.WinHttpRequest.5.1")
whr.Open("POST", "http://192.168.0.110:10000/sony/audio")
whr.SetRequestHeader("Content-Type", "application/json")
jsonbody := '{ "method":"setAudioVolume", "id":98, "params":[ {"volume":"+1"}], "version":"1.1" }'
whr.Send(jsonbody)
}

@root Very cool. Thanks for sharing the script.
