I'm unable to get audio to route to the 3.5mm jack
I am running an up to date osmc on an old but trusted Pi b (showing bcm2835 @ 850mhz), with osmc Bluetooth dongle (which fixed my initial play issues with a2dp)
I am pairing with command line as my apple devices don't seem to want to find the osmc Bluetooth.
Throughout this thread there are mentions of playing audio through hdmi and 3.5mm jack streamed from an iPhone or similar.
This is the bit I can't get to work. Pi is setup to output to both, and if I have both turned on then Kodi sounds do come out of both so I know both paths and my amp are working.
everything is as per install apart from one setting I found in this thread about adding dtparam=audio=on to config.txt. I tried the amixer posts but it wasn't recognised.
This thread mentions many people having this work but I don't think on my Pi version.
Any insights would be appreciated.
N.b osmc Bluetooth dongle and a2dp works great as advertised, it cuts out occasionally but that is likely due to power as it is running from the Pi and I need to get it a powered USB hub.
