我是用xfire1024推elite840
不撥任何音樂
戴上耳機就會有很明顯沙沙聲
就算把主音量給mute
還個沙沙聲還是在
我想，都把主音量給mute了
沙沙聲還在，這應該是電子元件中的thermal noise或其它雜七雜八的noise吧
請問這個沙沙聲是無可避免的嗎？
謝謝
音效卡推耳機時的雜音是無法避免的嗎？

找到一些重點。
1.把CD-ROM的音源線拔掉
2.音量控制中將CD音效靜音
3.麥克風也靜音
4.使用數位播放方式來聽CD
晚上試試看再來告訴大家結果。
剛剛去看terratec的美國官網，
在FAQ裡面找到有兩條是與我目前遇到的問題相關的...
Question 1:
Do I have to move jumpers and change dip switch settings before I install the sound card？
Answer 1:
To operate and install the card as such it is not necessary to move jumpers. But for reasons of flexibility there are two jumpers - the first jumper (JP1) enables the headphone amplifier at the first line output to be switched on/off, the second jumper (JP2) permits the signal level at the digital input to be changed over (TTL or S/PDIF). The card complies completely with the Intel/Microsoft specification. There are no jumpers or switches to be set for IRQs, DMA channels and addresses.
Question 6:
Background noise is continuously coming over the speakers, what can I do?
Answer 6:
When the sound card was being designed, value was placed on incorporating the best audio properties. Nevertheless, it is still possible that in certain computer configurations inserting graphics and video cards, hard drive controllers or even power supply units can have an effect on the audio signal. Generally, the built-in amplifier is very sensitive to this. Use active speakers or your hi-fi system on the line output. When installing the sound card in your computer, try to place it as far away as possible from the sources of interference mentioned above. Switch the microphone input to mute when not in use.
所以只有Line Out 1才有耳擴!! :eek:
那台灣官網上寫的：
擴大器 耳機擴大器，2 x 60 mW
意思就是兩個聲道各用一個囉?
真糟糕,
我還以為是可以同時推兩支耳機
