但是现在没搞明白ASIO时的音量怎么调节？控制台的音量控制完全起不了作用。只能靠Foobar的音量条工作。驱动本身有没有其它方法控制那个耳放芯片呢？) b5 o1 A1 R4 L

5. To keep the ASIO stream bit-perfect, the following two rules apply: & @4 p8 U, R) Y! ^3 d+ i(1) The ASIO stream has higher priority of using DMA buffer than other streams.

这样做有意义嘛？我调用foobar的音量功能岂不更糟糕。 # t, Z: o( z8 B9 C& Z I- x% I" m- {! ? B) I' D2 @: a2 H
