MLP decoding (foo_input_dvda) doesn't work with the new version: A track is starting to play but skips after the first second. Confirmed working in 1.4.6.
Found some sample MLP files and at least those played fine with foo_input_dvda 0.4.11.
I upgraded again to 1.5 b9 from 1.4.6 and now the offending tracks play normally. That is really weird, sorry for the bother.
