Check that:
• PC sound card, speakers and microphone are correctly connected
• the Mute button is not pressed
• the volume in and volume out settings are correct
• all cabling is connected
• the value of the Post Content Length in your proxy server is 1MB or more. You may need to contact your
system administrator to do this.
Incorrect configuration. Check the setting in the camera's Setup pages.
Sound card does not support full-duplex. For information on how to check if your sound card supports
full-duplex, please visit www.axis.com and see the support section for Axis camera products.
Too many users/clients connected. Try limiting the number of clients allowed to connect.
Low bandwidth. Reduce the Speed setting on the Audio settings page. Setting lower speed will reduce any
break-up in the sound, but will also increase the transmission delay. If running in Full-Duplex mode, try
switching to Half-Duplex mode.
Poor positioning of speakers and/or microphone. Relocate the speakers or microphone so that they do not
point towards each other, and/or lower the volume.
