What's the rootcause of noise and stuttering ? For normal playback, it should not have issues. If decoder didn't drop data, I think alsasink did it. By gstaudiosink mechanism, it will drop data replaced with blank data when data is late. I guess the rootcause is that. If that, I have no ideas except adding a queue before alsasink, and when queue is empty, pause the pipeline, it will not cause dropout, but still discontinous.

If I send MP3 data I have to set the buffer-time and latency-time to 10000 and 100 respectively to play without severe dropouts. However WAV files still have drop-out at a consistent rate (about 1 per 10 sec). Are there some general features I'm missing or is there some guidance on the buffer-time/latency time that would account for this difference?
