So this worked before you upgraded to the beta?

No problem with tvOS 11

Sounds like a beta os issue rather than hardware or cable issues.

I like the tech numbers on that cable: see below so that should not be the problem

I use a very short cable for testing but only to monitors as no 4k HDR TV yet


Specifications:

• Supported Bandwidth: 18Gbps
• Maximum Resolution: 4096x2160@60Hz 4:4:4 8bit
• Nominal Attenuation: 300kHz-825MHz <5dB, 825MHz-2.475GHz <5dB, 2.475GHz-4.125GHz <12dB, 4.125GHz-5.1GHz <20db

Have you tried tinkering with audio settings like set audio format to off and set audio mode to auto or 16 bit?

is it a Cable Test hang or a fail message ?

no information on dev forum on this for the latest update tvos12b6 ?

I have a lot of cables I want to test - some longer.
