RMAA了0404这卡，真恶心。

罗力

使用厂家rmaa预设文件

天知道他们怎么能测的，模拟口输出能力实在太弱 难怪他们说这卡直推耳机无力 line out>line in ，录音电平推到最大也只有-12db，且输出不平衡，所以说直连根本不能测。

绝种好男人

自己line out->line in不就自攻自受了么，成绩怎么会好

kcordnas

0404本来就不是拿来直推耳机用的卡呀……

YHX翼

RMAA本来就不能代表任何意义……

SORAYA

还是别玩内置卡了，没前途的，哪怕是万元级别的内置卡

fddf

0550使用者路过，表示毫无压力~

白色0404 USB飘过，同样毫无压力～
