It seemingly is latency. You speak into the mic and what you hear has
some delay compared with your "real" voice?
That has to do with the buffering of audio and depends to the used
hardware and the (possible) settings for the buffering, when using this
hardware.
If you use jack, than you can set the buffering by a GUI called
qjackctl.
The latency depends to the settings of "Frames/Period", "Sample Rate"
and "Periods/Buffer". Don't play around with "Periods/Buffer", for
professional cards keep the value at 2 and for your on-board thingy I
suspect you need to increase it to 3. Decrease "Frames/Period" and/or
increase "Sample Rate" to lower the latency.
