Use the decoder wrapper that was introduced for video. This removes all code duplication the old audio decoder wrapper had with the video code. (The audio wrapper was copy pasted from the video one over a decade ago, and has been kept in sync ever since by the power of copy&paste. Since the original copy&paste was possibly done by someone who did not answer to the LGPL relicensing, this should also remove all doubts about whether any of this code is left, since we now completely remove any code that could possibly have been based on it.) There is some complication with spdif handling, and a minor behavior change (it will restrict the list of codecs to spdif if spdif is to be used), but there should not be any difference in practice.
