I'm hoping there a some bright audio experts on here! My comms panel has a 3mm jack input for aux in. If I connect my Pilotaware to it via a 3mm to 3mm cable then the traffic alerts are at the perfect sound level on the comms with the default Pilotaware volume level setting. If I remove the cable from PIlotaware and connect the same cable into the headphone socket on my tablet running Skydemon for the intelligent traffic alerts then I can barely hear the voice alerts even with the volume fully up on the tablet. If I listen to the tablet via headphones then it is plenty loud enough. There must be some kind of sound level difference. Any ideas? I'd like to use the Skydemon alerts but can't for this reason. many thanks.

I'm not a bright audio expert but I did have the same issue. What sort of tablet? This fooled me too until I realised that Android (my version anyway) has three different volume controls and the Skydemon voice alerts are controlled by the "media" one. This is not the one that the side buttons normally adjust (on my Nexus). You need to use the buttons while it's actually speaking, or else access the dropdown that shows all three sliders (don't have my phone to hand so can't recall how you do that). You can force Skydemon to speak from within the setup menu.

I have all three volume controls at max, it's not that unfortunately. On my tablet I press the vol button and it presents a drop down where I can list the three volume controls and slide them to max, all set as high as they will go.

I'll check that and make sure I have the correct plug types, although it works fine when plugged in to my Pilotaware so I think they are.

Theres a few discussions on the PAW forum about the PI output, it is 3.5mm, but is TRRS (so Tip, ring ring sleeve) and so has Left, right, ground - and video.

What I did is wire up a TRRS plug and cable to the Mic Jack input to the rear seat inputs on my intercom and adjusted the volume up on the Pi.

You may have been ok with a normal 3.5mm audio jack (L/R/Ground) in the Pi, but it may be best to get the correct plug at that end - if your going into a tablet insead of the pi, then it may not like a TRRS type, if thats what you have got. (You may have 3.5mm mono, or stereo, or TRSS!)

Ok cheers for that, sounds like I need to read up on these connection types and number of rings etc. Hopefully I just need a different lead then.
