Unable to stream 16bit wav file to speaker

[Walter Lucetti]

Hi all,

I have a problem with GStreamer 1.9.90 and a 16bit PCM mono channel wave
file to be played.

I'm using this very simple pipeline that works very well with 8bit file:

gst-launch-1.0.exe filesrc location="C:/Users/walter/Desktop/00000002.wav"
! decodebin ! audioresample ! audioconvert ! autoaudiosink -v -e

With 16 bit file (S16LE to be precise) the output is a long noise.

this is the output I obtain with "-v" option... I notice that recognized
format il "8U", but I'm not able to force it to 16bit anyway:
