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

% V4 T- u9 e1 _! a$ d1 P- r% i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？

' C. ~. H! g- s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？: O: p* x8 S$ y; v! {
尽管+18明显很有推力，但感觉好像有点过头有点吵的感觉。: x, ?. Q5 _1 G0 v' m: i, ?( H

2. Supports one ASIO playback stream (maximum 8 channels) to analog output.+ R. x3 D I( y. [
3. Supports one ASIO recording stream (2 channels) from analog input.

5. To keep the ASIO stream bit-perfect, the following two rules apply:
' N1 ~6 |- N- ^* n( m(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.% b6 a$ A3 V6 H# R
(2) No volume control is available for the ASIO stream.
