2. Click "Start"> "program"> "attachment"> "entertainment"> "recorder" to check whether sound exists;
3. click the audio console at the bottom of the Channel staff list to go to "sound card settings" to see if you can hear your voice. Then, select "sound input" and "sound output ", check whether there are any waveform fluctuations in the earphones and microphone tags below,
