alsa modules are noisy and silent after several minutes of use

[buda servantes]

gst-plugins-base | 1.4

I use gstreamer to connect two audio interfaces (hw:1 = tvtuner and system
sound). 
It's work nicely but after a few minutes, I get noise (the sound is
completely distorted) and becomes silent. 

This is a complete pipeline that breaks:

audiosrc device=hw:1 ! tee ! queue !audioconvert ! audioresample !
autoaudiosink! queue ! encodebin ! filesink

I tested also with:
 * gst-launch-1.0 v4l2radio device=/dev/radio0 frequency=106600000
 * gst-launch-1.0 alsasrc device=hw:1 ! audioconvert ! audioresample !
alsasink

and results is same.
