Subject: spdif input, source synchronous?
Date: Thu, 8 Nov 2012 10:10:41 +0100	[thread overview]
Message-ID: <603ABBBDFF6140989F91BF7793F25E83@mediascore.mediascore.de> (raw)

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
