Ogg files are not played gaplessly with 2.9x
 

You know that ogg vorbis format is gapless itself and Winamp 2.81 cope with this perfectly, providing absolutely gapless playback. However, after I installed 2.90 (and 2.91 further) I noticed that very subtle but still audible gaps appeared between the tracks that were otherwise continuous. After I put the out_ds.dll from the "old" 2.81, I was again happy. If I am not wrong its version is 2.2.6 in Winamp 2.9x and 2.2.1 in Winamp 2.81.

Sorry if this is duplicate report, I have already searched for it.
