Actually, the sampling does perfectly capture the analog signal.

More precisely: the digital sampling is sufficient to perfectly recreate the analog signal. That is the actual purpose of sampling.

The fact that the digital sampling can do this was scientifically proven decades ago and called the Nyquist theorem.

You keep looking at an arbitrarily designed 2-dimensional abstraction of digital samples, and irrationally believe that these drawings somehow represent how the reproduced audio will actually sound.

It's as incorrect as believing you cannot correctly assemble an Ikea shelf, because the directions do not display the wood grain on the planks.

The "losses" of information in digital sampling at industry-standard rates & bit depths are so small that it's physiologically impossible for human ears to discern them.

Here is a link that describes A to D conversion.

Check out how a sample does not completely capture the analog signal perfectly, thus there are some losses in the A to D conversion.
