Remote volume control possible?
« on: February 25, 2016, 10:36:05 am »

I have MC set to fixed volume output. So that the volume control gets done at the receiver which is the last possible point in the chain.

In this configuration, it would be really cool if MCs volume control slider and buttons could, instead of adjusting the digital volume, rather be connected to an i/r blaster that commands the receiver volume.

Is that doable? Is it "too easy" ??

I am thinking that MC's volume buttons may be able to drive something like this:

MC already supports an IR-blaster, so the framework is there. I really like the idea, but it has hurdles as far as I can see, one very easy to overcome, and one that is a bit more difficult.

1. It is a possible "one click to destroy your equipment"-setup, as running the receiver on 100% can destroy your speaker (and/or hearing :)). I suggest volume limiting is as a default automatically put to "on" if the function is activated.

2. You set the volume to 37% in MC, what is the blaster command for that in receiver? Volume up and volume down is easy to find, and learn for the user. A given volume level can be more difficult.

Elvis makes a really good point.  Some buttons for receivers are very easy to automate.  Selecting an input for example.  That's not ambiguous.  But something like volume level is extremely ambiguous.  Most receivers and pre/pros only have volume up and volume down, which are relative commands.  I don't know of any that have absolute volume commands like "go to 30%".  Which means that implementing this feature would be pretty strange.  I'm not sure how you would get it to work reliably.

During my research, it seems like quite a lot of receivers actually have commands for absolute volume, even though the remote doesn't have the buttons, but the commands are not always well documented (you often have to google and search on forums with remote commands and so on), and often you only find 10% 20% and so on, I don't know how easy it is to infer the inbetween-points from them.
