Encoder line out

If I use the encoder and listen to the stream the sound is good but when I listen to the default audio output the sound is with hick ups.
It gets beter if I bring the latancy back in stereo tool but there is no problem when I listen to the stream through the web player ,so what am I doing wrong?
Or is there a beter way to check the sound quality ,listen to the broadcast stream has a 30 sec delay and to make adjustments and wait 30 sec issent workable
There is also an aircheck and in the tape the sound is also good , it only sounds bad in the default audio output
In the encoder is a vst from stereo tool

Increase the buffer size of the playback device.
