Sharc Processor with LG CX and PS5

[BengalCatKilo]

I recently purchased a eARC convertor called the Sharc from Thenaudio. Their claim is to be able to extract the uncompressed audio codecs from devices hooked up to the tv and then thru their box and back to your receiver by using the tv's eARC output which connects to the Sharc processor and then uses a HDMI input on your older receivers.
I'm primarily using it so I can run my Sony PS5 directly into the LG CX's HDMI 2.1 input to take advantage of all the newer gaming features. And with the Sharc I'm suppose to then be able to send the audio signal back to my Anthem MRX 720 receiver and get uncompressed audio codecs like Atmos or DTS: X. So upon hooking everything up and using The Hobbit 4K as a test disc, I get the following info. Attached pictures show info on the CX using the freesync menu, the display menu from the CX, the input signal on the Anthem with the sampling rate. So upon testing it seems that it's passing the Atmos signal as the display says Atmos 48kH Lossless. So I'm assuming the Sharc is doing its job, so I'm looking for confirmation that I did everything correctly.

Pic #2 does not come up so can't see if atmos is coming over to the receiver. No worries, but don't confuse uncompressed with lossless. Dolby TrueHD and DTS:X are lossless but are also compressed. If the Anthem display shows atmos, then atmos metadata is coming over with the TrueHD track. So, it worked! Joy!

Ok, see fixed pic now. Seems all is well.

Thanks for the reply, my only other question is 48khz a normal bit rate for a 4K UHD Blu-ray movie as I don't have anything else to compare it to.

That is not unusual.

Technology Dolby Audio Dolby TrueHD | Dolby Developer

Dolby TrueHD, also known as MLP, is a lossless audio codec used widely on HD and UHD Blu-ray Discs. Dolby TrueHD supports up to 24-bit audio and sampling rates from 44.1 kHz to 192 kHz.

A better question is if it is 96khz does it make any difference? It's not a bit rate, it's a sample rate (in that a sample rate is twice the possible highest frequency in the content). Bit rate would be 16, or 24, etc and is more important in the recording process than the reproduction process....
