首先,这是我的 aplay -l 的输出:
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
我使用第一张卡,因此我更改了配置:asound.conf:
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
ctl.equal {
type equal;
}
pcm.plugequal {
type equal;
slave.pcm "plughw:1,0";
}
pcm.!default {
type plug;
slave.pcm plugequal;
}
〜/ .asoundrc:
ctl.equal {
type equal;
}
pcm.plugequal {
type equal;
slave.pcm "plughw:1,0";
}
pcm.equal{
type plug;
slave.pcm plugequal;
}
所以如您所见,设备已按应有的方式设置,
但当我运行 alsamixergui -D equal 并将所有条形图调低时,
声音仍在播放,没有变化。如果我只运行 alsamixer,我可以
正确调整主音频。这里可能是什么问题?
