Volume up and Volume down don't work #8
Description
Okay, so they probably do work... But I'm not sure how. They aren't part of the device class, so I'm not 100% sure what they do. I can't run, for example tv.volume_up(), and running cec.volume_up() just returns true.
Should these be able to send volume up and down commands to the TV?

cec.volume_up()andcec.volume_down()are wrappers around the volume up and down functions that are part of the libcec API. I think the underlying libcec functions are sending volume up and down to the cec AV device with address 5. (Usually a receiver).I don't currently have an API for sending user controls, button presses or raw commands to a specific device. That would probably be a good addition to the API.
I don't have time to write that API at the moment, but I will gladly accept a pull request.

Just thought I'd add my 👍 to this.
Edit:
vol_up()does actually work for me, I had a configuration problem.Edit: found a weird quirk (read: bug). The volume functions only work after I call

@RSully Did you need to do anything else to get the volume working? I've tried running list_devices() first and the volume controls are still not doing anything.

@brad999 I actually switched to using the C++ API directly. My limited implementation is here.

@RSully I found the same - vol doesn't work after cec.init(), but does work after cec.list_devices()

I suspect this is a bug/feature in the underlying libcec API. It probably needs to detect which devices are present before it knows which address to send volume messages to.
