it's actually useful only in one case with Kodi... when Kodi tries to set 24p calls 1080p24hz, the internal mechanism tries to adjust it to 1080p23hz (as long as you have codesnake patch included), calling directly that video mode would avoid the double change but when you call 1080p23hz some other parts kicks in to adjust pll/clocks in the hdmi driver, that's the part that make the audio stutter.

edit: in fact I have tried this morning

Kodi refresh rate switch disabled + manually switching resolution to 1080p24hz (tried also 1080p23hz) before starting video playback
- TrueHD - stutters with /sys/class/tv/policy_fr_auto enabled or disabled at 24hz or 23hz
- DTS-HD - same as above
