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.

Subject: [gst-embedded] noise and stuttering
I'm trying to create an audio player on an IMX31 target and I've found a
discrepancy in the output of various formats. 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?
Linux 2.6.22.19
gstreamer 0.10.17 (open-embedded)
gst-launch filesrc location=<file> ! decodebin ! alsasink
buffer-time=10000 latency-time=100
