I think you're doing the right thing by analyzing the digital stream carefully and checking the electrical components around the codec. There's usually a ton of things to consider, but it's hard to tell what to look for without having the same hardware. Still, let me know what you find :) Daniel _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
