I bought a logitech desktop 600 and noone can hear

Try plugging it into different ports, not all USB ports are powered.

Double Click the speaker icon on the right hand bottom ( next to clock ) of the desktop screen.Click options, then click properties. Form the drop down list tick MIC.Now your **** socket is active but by default the MUTE box will be ticked. Untick to enable it. Adjust MIC level for clear sound.

Hi Warp you can not use any other mouse with your Logitech Easycall Desktop receiver, but with the additionnal mouse's receiver connected you should not meet any conflict using both at the same time. Thanks and have a nice day. Crenshow

the tab in control panel...not sure what you're referring to changing... but make sure you change the sound input device from the default internal mic/input to the logitech

throw it in the trash. I got one too. Their website is useless. No drivers anywhere. Help line is super long distance. I will never buy logi tech again.

go to control panel - speech recognition[sic] and then a sceer comes up where it asks questions 2nd one set-up my mic. It worked for me and i use vista 64(sucky)

there is no other option to let the peoples to hear your played music, by putting music on speakers and hear them through mic.

I had the issue. Bought second hand motherboard on ebay and it fixed the problem. Apparently its a common issue with the motherboards used in the Scaleo 600

Mine did the same thing, only mine was at noon. Press the "FN" Key (between the left Alt. and left Ctrl Keys) and then the F11 Key. This will turn the alarm off then on again if the F11 key is pressed a second time.
