在未使用无线键鼠套装（罗技M270）,USB耳麦（现代UFO）一切正常，接了无线的键鼠后，耳麦开始出现杂音，更换USB接口没有效果，请高手指点，谢谢无线接在前置接口，耳麦在机箱后接口

点右下角的小喇叭（右键）有个录音设备,里面有好多麦克风,有一个就是你的USB麦克,点右键-属性-级别看看有没有开麦克风增强,找到开麦克风增强的那个麦克,把增强关掉,或者直接禁用.如果还不行,换个耳麦试试

你说的方法我试过，我没设置过增强，没效果。不过还是谢谢你的热心帮忙。拔了键鼠，杂音就没了

问了一下专业的人员，不排除你的无线键鼠信号与耳麦有干扰的可能，你不妨换一个耳麦试一下，或者把键鼠和耳麦换一台机器试一下

有源HUB，能解决这个问题么？我觉得应该是信号干扰或者是电流的声音

ty1394942	2012-03-03 23:53
不同时使用，键鼠、USB耳麦都正常

不同时使用当然没问题，照我说的试一下嘛！如果现象依旧，那你只有换设备了

万分感谢，有问题再请教您，谢谢

ty1394942	2012-03-04 00:07
用普通插声卡的耳机没有任何问题

jiowana1	2012-03-04 12:18
呵呵 USB接口的音响耳麦，在使用过程中都会出现杂音的

johnsmith99	2012-03-05 11:55
建议给耳麦加USB卡扣磁环。

lzsuperman	2012-03-07 09:58
可能是受到干扰吧你用USB延长线试试放到桌面上

yoooji	2012-03-08 16:47
重装一下驱动！

2.4G的信号干扰了，你的无线耳麦质量不咋滴

好迷梦	2012-03-11 16:12
恩这是USB供电不稳导致的，是USB音响的通病

gexuan	2012-03-15 08:01
鼠标干扰耳麦舍掉一个吧或者换个品牌的

shuaigelaozi	2012-03-19 01:12
无线的键鼠用无线电肯定有干扰源，要是经常用耳麦最好还是用有线的，这样才不会互相干扰。
