[SOLVED] I rang Richer Sounds, they provided me with a solution that's so obvious now, although not the one I wanted, but it works, and was a bit of a faff.
They've heard about this issue with HDMI connections before, and said it's to do with the digital handshake, and should be able to be solved at the Windows end by changing settings - I don't know why as it didn't happen when plugged into my TV.
Either way, I couldn't find any settings that sorted it. Richer Sounds suggested Googling "Realtek audio Latency Delay Issue" as I use Realtek. Couldn't find anything about playback, only stuff about people recording music through mics and instruments.
It crossed my mind whether it could be some other audio driver or software causing the conflict, I had MSI Nahimic (something to do with speaker and microphone setup) I disabled it - still no joy.
THE SOLUTION - ANALOG!!!
1) I went to PC World and bought a Logik 3.5mm Jack > RCA (double ended (right and left / red & white) for a tenner.
2) Plugged the 3.5mm jack in Line Out into the back of my PC's motherboard
3) Connected the red & white RCA ends into the Audio In 1 port on the back of the AVR
4) Went into the settings in my AVR and changed the Audio source to the analog Audio 1 Line In: Press Home on the remote > System Setup > Source > Audio Select > Set Audio Select to Analog (I found setting it to Coaxial also works).
5) Make sure your hardware assignments for display & audio are the same - I'm using "BD/DVD" for both, even though it's a PC, you can rename them. Basically by default BD/DVD = HDCP In 1 and Audio In 1.
6) Test by right clicking Volume icon in system tray > Playback Devices > Right click "Speakers" (Richer Sounds man said it might say "Line In" instead, but it didn't for me) > Test. I DON'T know whether you HAVE to disable your normal HDMI playback device to get it to work, mine was "AV Receiver: NVidia High Definition Audio". I disabled it just for good measure. Don't know if it was necessary.
And now I have pause free music - I can hear Spotify songs from the beginning, game intros from the beginning, and actually hear Windows error messages!
Hope that makes sense!

Tell me about it with the unplugging stuff... My AVR is in a cubby in an entertainment unit below a precarious Ikea glass shelf with my modem and Kodi box on, all wires going through a small 4" hole, and I have to get as much of my body inside the cubby hole as possible - it's a right task!
I had a Yamaha for 5 years, great piece of kit, but I always thought the front of the unit itself and the remote were ugly, and I don't think I ever used it to its full potential. Also there was quite a lot of buggy things with it I never got round to fixing - I could never disable the auto shutdown, if I switched it on before my PC it liked to mess about with my resolutions something awful.
I'm yet to experience any of that with the Pioneer, it looks better IMO, and has greater functionality than the nearest priced Yamaha at a lesser cost.
