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?7 }. U& C: a6 h1 o

6. When there are more than two ASIO applications running, only one application gets the right to use the hardware resource. This is based on “first come, first service” rule.

这样做有意义嘛?我调用foobar的音量功能岂不更糟糕。
