I’m not having any luck troubleshooting the audio problem on my own. Is this part normal:
2021-08-08 06:25:32.217 T:3344 INFO <general>: CAESinkALSA::InitializeHW - Your hardware does not support AE_FMT_FLOAT, trying other formats
2021-08-08 06:25:32.217 T:3344 INFO <general>: CAESinkALSA::InitializeHW - Using data format AE_FMT_S24NE4
Not really a solution, but I’ve got things in a good-enough state for now by hooking up an old receiver between the Vero 4k and the Vizio TV. The receiver doesn’t support 4k so I lose that ability, but at least the audio is working.
I would be curious to know why audio doesn’t work with the vero connected directly to the Vizio TV, but at this point it’s more of an annoyance than a problem so don’t worry about it.
