Believe it or not, I've only just (bothered to) get ALSA working on my system (Debian Sarge snapshot a couple of months old) I have a M-Audio DiO 2448, and the primary reason for choosing it was for S/PDIF digital input. That worked with the OSS drivers (paid for...) - now how do I control the S/PDIF input with ALSA? The driver module is snd-cmipci. -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
