The limitation of the chip is a given. That's what the manufacturer offers.
Because the typical application for what it is made for, usually won't go higher then 48kHz. That 48kHz limit you'll find in most mobile phones, tablets, Ubuntu,Windows asf asf. They all resample to a common samplerate of usually 48kHz by default. It seems the chip doesn't provide an automatic DSP bypass or DSP OFF for samplerates > 48khz. This could cause trouble. In filters that a. degrade the sound and b. doesn't work at all. A driver needs to put a chip into modes that a. avoid malfunction or b. tells the OS or better the app that certain samplerates are not supported if these would cause malfunction. Example: There could be a very simple mod from a driver perspective: 1. For samplerates higher than 48khz the DSP/filters are turned off or bypassed. Obviously the chip needs to provide that "switch". If there's no such thing 2. Don't allow samplerates higher than 48khz. A proper resampling of samplerates >48khz to <48kHz on the LMS server probably gives better quality then running an inadequate filter on the PCM5122.
