Make sure to pick the correct version!
First version:

Enabling DP audio stall fix is necessary to play audio over DP HBR2. So,
let's set this bit right before enabling the audio codec. Playing audio
without setting this bit results in pipe FIFO underruns.

This workaround is applicable only for audio sample rates up to 96kHz. For
frequencies above 96kHz, this is insufficient and cdclk should be increased
to at least 432 MHz, just like BDW. Since, the audio driver does not
support sample rates > 48 kHz, we are safe with this fix for now.

Mind not be enough. Really wonder why it does not support 44.1 khz. Will have a look.
