1-port HDMI 2.0 A/V splitter recommendations

[Largo]

Hello,

We changed our TV and we now have this setup:
Shield TV Pro (HDMI Out) ---> (HDMI IN) 4K TV (HDMI ARC) ---> (HDMI ARC) Denon 1911 AVR

I obviously lost HD audio.

to get my HD audio back, I'm thinking of a HDMI splitter. The new setup could look like this:
Shield TV Pro (HDMI Out) ---> (HDMI IN) HDMI Splitter

Splitter (HDMI Video OUT) ---> (HDMI IN) 4K TV​

Splitter (HDMI Audio OUT) ---> (HDMI IN) Denon 1911 AVR​

specifications I can think of:

• I just need one HDMI input on the splitter
• the splitter must comply with HDMI CEC, I want to keep using my Shield TV remote control to turn shield+TV+AVR.
• the splitter must support HDMI 2.0
• no lip sync issue
• can work without a remote

something reliable that works perfectly with dtshdma or dolby TrueHD.
I see a lot of these splitters on amazon but I'm suspicious of the reviews.
