How to setup S/PDIF Input

[Franz Schenk <schenk@informatik.uni-goettingen.de>]

Hello,

I want to use the S/PDIF connector on my Abit AV8. The chipset in use is an VIA 8237, the codec is Realtek ALC658. 

I've done some research on the web, mainly in the alsa-archives. But most of the information is concerned with how to setup S/PDIF output. The most specific document from the alsa-project seems to be this one: http://alsa.opensrc.org/via8233. But wrt sound signals via s/pdif-in there is no useful information.

Maybe any of you has managed to setup s/pdif-in properly on the same board or with a similar configuration?

Thanks a lot in advance for any help!

Franz
