The issue of HDMI audio jitter has to be dealt with on the receiver side, where the audio clocks are derived from the high frequency TMDS clock with its own timing characteristics. This is where most of the audio clock jitter is coming from due to use of high bandwidth PLLs with very small jitter rejection abilities.

The UDP-205 features a high-stability, high-precision HDMI clock and a special HDMI audio jitter reduction circuit. This unique design significantly reduces jitter and eliminates timing errors, allowing you to enjoy your music with increased accuracy when you use the audio-only HDMI output port for connecting the audio signal.

As a result, the HDMI audio jitter reduction circuit can improve the sound quality of PCM and DSD audio directly. For bitstream audio in compressed formats such as Dolby Atmos, Dolby TrueHD, DTS:X or DTS-HD Master, the jitter reduction benefit depends on whether the decoder design in the audio processor/receiver uses a synchronous or asynchronous clock.

HDMI indeed doesn't treat audio as a first class citizen, its clock must be derived from the video clock. On the other hand we are talking about high tech TDMS links at up to 10 gbit/s rates! To be able to transmit at these rates engineers had to solve much worse problems than your usual grain of jitter.
Is HDMI asynchronous (does clock/jitter matter)? | AVS Forum

You have HDMI clock itself varying to some extent due to clock instability, cable induced jitter, etc. You have interferences inside the receiver which cause cause their own jitter. There are solutions to this problem of course but they get complex and expensive since you only want to filter the jitter, but not true changes in source rate.

A Deep Dive into HDMI Audio Performance ... Now, even though jitter is a timing clock problem, we don’t measure its effects at the clock input of the DAC. The reason is that we can’t access that part easily anyway and at any rate, the DAC is supposed to have circuits in it (called PLL) that help to reduce its rate (in theory anyway; see ...
