5. To keep the ASIO stream bit-perfect, the following two rules apply:* W0 C3 ^1 @$ O4 V
(1) The ASIO stream has higher priority of using DMA buffer than other streams. That is, when the ASIO stream is played, other streams cannot be played. * ^1 n9 F$ H( v4 H1 F(2) No volume control is available for the ASIO stream. ; n# ? |: ]" p1 `2 J6 ]8 K0 l% P6.

我用WIN2008R2,跟WIN7 64位系统差不多,老虎卡驱动里的音量控制能控制ASIO声音的大小.作者: adsee 时间: 2010-9-13 21:46
驱动里音量调节最好把它开到100%,否则音质会不是很好,粗和涩,开到100%则不会,这个答案你满意不?作者: adsee 时间: 2010-9-13 21:46
声音的大小调节foobar就行了.作者: xusphere 时间: 2010-9-13 22:07
