The SPDIF input problems are known (at least to me) and not specific to the xfire card. The main problem is that I dont have enough of technical info about to implement the SPDIF input part. The only answer I got from a developer at Cirrus regarding the SPDIF input part was something like: "yeahh, the SPDIF input needs some special treatments but in this moment I dont remember exactly what" now several months has passed and I have not heard a single word from Cirrus (got no responses to my mails at all anymore ...) So, so i am afraid that it wont be better than that for the moment ... /Benny ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/
