I want to check whether system has sound card installed or not, and this i want to check in my website. So this whole process will run in background completely ünknown to user. As soon as they connect to our website this control will secretly check as the rest of the site loads. If the result of the control returns a results that they have speakers and the volume is turned on then it will trigger a sound.
This is for web based applicatiojn.
Please help me how do i check this? in any language asp, php, asp.net, java etc..
Thanks in advance.
