There is a patch pending since some time, that Michele was working on
recently. From what I have seen he prepared a backport that will go into
14.0 when ready.

Perhaps we should understand and test your use case. I was testing the day
before on a VM and older Notebook D520 with the default multimedia keys
(usb keyboard with MM keys and MM combination FN+<n>).

I see on the internet that on the Thinkpad X1
        FN+1 = Mute
        FN+2 = decrease volume
        FN+3 = increase volume

So it seems that default MM keys are being used on your end. I believe the
patch will work for you, so be patient or if you can recompile the code,
you could help testing it :)
