因为懒得去折腾耳放和解码器所以又入了张老虎卡

耳机是HD600,现在在和原来的MIA MIDI+国产HEF188对比听中,暂时感觉良好9 D( d9 d. g7 ^" }+ v% ^

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?

另外顺便关于耳放增益的问题,耳放选择关键是阻抗匹配,那么HD600(300ohm应该选+12db(64~300ohm)还是+18db(300-600ohm)比较好?

PS:在驱动说明里找到的答案

5. To keep the ASIO stream bit-perfect, the following two rules apply:

(2) No volume control is available for the ASIO stream.- i& N) F9 C9 t% @
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.; |9 o7 I9 {2 q

这样做有意义嘛?我调用foobar的音量功能岂不更糟糕。
