It would seem to reduce the number of calls to arts if we waited for a minimum amount of data, not sure if the input size of each chunk of input data is large enough to make this check pointless or if it won't hurt performace making the additional calls, just wanted to point it out.  The issue with OSS appears to be that for some drivers the fragment prior to the last one isn't played if the last fragment isn't complete, line 1398 of wineoss/audio.c, I'd be inclined to think this isn't something to worry about with arts.
