[Help] Syncing Ashes and Diamonds (1958) 2005 Criterion DVD mono to 2021 Criterion Blu-ray

[Yarp]

Second Run has also released a new BD in the UK last year, although they sourced it from a 2K restoration instead of Criterion’s 4K. Might be interesting to track it down and compare the audio.

Someone on blu-ray.com said this about the Second Run audio though:
The audio still has that strange timbre with a subwoofer activating "thump thump thump" on footsteps that was present on the Arrow release

So sounds like there's a good chance it's nothing great.
