Hi Developers,
Does anyone know how the SPDIF input is working on HDA? Is it using a source-synchronous data transfer over HDA? In my arrangement (ALC886) I can set up any rate and I am receiving a rectangular “resampling”. – is this a bug? will this stay? so I can use higher ratio and some kind of software PLL to recover input rate?
How can I read presence and rate of the signal? Verb – Get Digital Converter Control 1,2 is good thing to have, but I need “carrier-detect” and maybe rate to feed back to Alsa on setup.
I hope someone knows this – even if maybe spdif input is not very popular.
Regards, Rafal
