Is that definitely the case? My telly has an optical port I think, but if there’s going to be audio lag then it’s a waste of time.

Feel free to call me an idiot here but isn't the whole point of optical that it's light so travels at light speed so adding a few feet of cable shouldn't add any perceptible time?
I suppose I'm lucky in that as a headphone user I should be fine and in fact hopefully I can finally use my fancy pants Sony wireless headphones as the PS4 or Xbox doesn't accept them.
It will ultimately depend on how the signal is handled between each device for how much delay is added, but whatever happens there will be delay because something can't just appear somewhere else instantly. At least until a teleporter is invented.
If the audio from the console to the TV via HDMI and then from the TV to the speakers (optical) remains in digital form from end to end then there will be a delay (because it's passing through longer cables and the devices themselves need to pass the signal on to the next, perhaps through multiple circuit boards.
If the signal converts to analog at any point before the speakers convert the final output to analog then they'll be bigger delays because it would need to be converted back to digital during it's journey
It would affect games that require quick responses via audio, such a rhythm games. Shootey bang bang CoD games not so much. For audio, this generation (X1 and PS4) was actually a step back compared to last gen because of the removal of analog audio output from the consoles (being digital only the audio has to be converted to analog at some point so we can hear it, that process incurs time). It added latency to the audio outputs compared to the options we had on 360 and PS3. The potential removal of the optical output on the new Xbox would again set audio latency back further depending on your setup at home.
