Motherboard jumpers inserted the wrong sound card lead to failure
In recent days, a good friend of mine has just installed on the computer not long impatient火燎find me, and said: “The computer startup sound, sound card driver and reinstall the operating system will not work.”
Troubleshooting: Open computer, a smooth access to WinXP. The lower right corner of the desktop taskbar no small speaker icon (check “will be the volume icon in the taskbar Add” check), in “My Computer” Right-click into the “Properties” in the “hardware” page, See “Device Manager”, there is no yellow question mark alerts, sound card, also completely normal. Entered the “Control Panel”, click on the “Sounds and Audio Devices,” found that there “will be the volume icon in the taskbar Add” No打钩. So hook, the Desktop icon on the taskbar volume appeared. Open Winamp music player, with the players a little progress bar to move, the main interface left visual plug-ins are also keen to beat the music, but to connect better speakers still no voice.
It seems that some of its initial wrong, all the normal sound card settings, but no sound, software, no problem. Appears to be hardware problems. Unplug the video card, sound card carefully examined whether the exposure to bad, suddenly took note speaker placed next to two small jumper caps, “This is come from?”, “I said yesterday, when loaded with built-Modem careless touch out, do not know where out … …. ” I pick up the motherboard manual to find inside jumper with related note. In the sound card settings page suddenly see this sentence: “If you do not want to use pre-audio, 5,6,9,10 must take a short jumper, this would signal output to the audio interface on the back.” It seems the problem here
Original piece of MSI motherboards support its audio front panel (the front of the box with the majority now have front audio jack that is different from an ordinary audio jack chassis lead only to the audio sound card jack lead to the front of the box, to extend the line role), if we want to have a voice behind the audio output jack to be a short jumper then 5,6 and 9,10 (Figure 1). I find the motherboard PCI slot next to the little jumper, was found empty above. There is no doubt that a friend when disassembly Modem built to碰掉careless, because friends do not have to buy another MSI audio front panel, so the author directly to the two jumpers on the cap placed in the provisions of position. Power boot, with the entry of WinXP, familiar and pleasant voice sounded, and the original sound card that is causing the reason for not audible.
