ad_spdif: set codec params

[kasper93]

It seems that we decode small portion of the audio to determine codec params. We can remember that information.

Fixes: #14178

@mitzsch: Could you test this to see if it is what you expect?

Thanks for your work! Unfortunately, I´m off my AVR system again for some time - so I can only test with -ao=null.

It now shows => or

So it now shows the codec (nice!) but not the profile. Would it be possible now to also show the profile?

[kasper93]

Updated, there was not so correct assumption, that got outdated over the years.

[mitzsch]

Perfect! Works!!!

Edit: On DTSX Files it only show DTS-HD MA (same file) - all other DTS modes (HRA/MA/DTS96/24) are correctly identified.

To little data is decoded while probing probably. But since, the decoding anything in the first place is not that great, I doubt this will change. Unless it is required for proper playback.

Also maybe just in case it is in fact detected, it would be good to add those profiles. But since it is not detected anyway. I would not change that, unless there are playback issues.

Ok, I see, but I guess it's fine with the new state introduced by this commit. Having it to show the codec + profile is a nice addition. Thanks! :)
