the first pipeline creates a raw audio file without and metadata.
Thus you need to check the negotiated caps (e.g. signed-16bit, 1
channel, 48khz) and use a caps filter on the 2nd pipeline after
filesrc to add the format info again. <br>

The problem is the ouput sound is a beep and not the
original sound, if i parse the first pipline to alsasink it
plays fine however, what am i missing ?<br>

if you give some more context we might be able to suggest you
alternative approaches.<br>

Basically i am looking at playing, seeking and mixing audio
together with as little delay as possible, so any suggestions
on pipelines for this would also be appreciated, but i would
like to understand what may be the cause with the second
program playing a different noise.<br>
