for the isochronous transfer model, so here the short packets processing can be a point of

As mentioned above the sample requires a sound source and a sound output Device. The
microphone is a good example of a sound source. Other sound sources can be connected
to the Mic-In socket (in case of microphone) or Line-In (TV Tuner as an example). The
sound should be heard through the sound output Device (speakers). There are a number
of possible causes of missing sound:
The following figure shows right Line-In and Microphone Balance setting.
If the sound source Device is working correctly, check the ‘Mute’ Line-In and
Microphone Balance settings. This ensures that no signal should appear on the sound
output Device from the sound source input. Otherwise an echo will be heard during
sample application execution.
Next go to Options menu and select Properties; check Recording box and press OK, the
following dialog should appear:

The microphone line (or Line-In) is muted.
