系统声音系统默认的是这个：

linux 下的 150% 还不如 windows下的 40% 呢，水的一批

我用 u盘里的 ubuntu的 23.10 test 模式试过了，也一样但是比 deepin v23 好不少，也不用开150%

，100% 即可。

但是 我把 deepin 选择了 pipeWire 模式了 还是 一个样子，看来还是 deepin usb 声卡适配 有点问题的

应该不是底层驱动的问题，物理通道是正常的，系统侧alsa组件的配置那块可以有优化的空间。

最后我还是 使用了pulseaudio 引擎了，

修改了配置文件，让他支持采用 24位，192khz 采样率，但是还是声音小，

系统100% 音量 和 cd 100% 音量，也就才相当于 win11下的 40%音量而已

有60%的音量损失

以下是我的 /etc/pulse/daemon.conf 配置：

pacmd list-cards 信息发下呢

也可以执行下alsa-info然后把信息发一下（默认会保存在/tmp目录下 alsa-info.txt.xxxx）。

最好把ubuntu下也发下。

alsa-info 看附件把，太多了 超过字数了

alsa-info.txt.zip

flat-volumes = yes 这一行没事还是注释掉吧

高采样率一般改一下默认采样位深，采样率和次选采样率就可以了

default-sample-format = s32le
default-sample-rate = 192000
alternate-sample-rate = 48000
default-sample-channels = 2
default-channel-map = front-left,front-right

最下面两行没必要放出来，注释掉好了

另外，如果解码芯片不是特别强悍，不建议32位采样深度，芯片压力大，相当于处理器烤机？

24位足够足够了，绝绝绝大部分人听不出区别

我试了一下 用 30欧的 耳机，推理能推得动

看来 linux 下 这个 cd 耳放模式，推不动500欧的耳机
