统信uos系统怎么没有声音？统信UOS1060上替换开机音乐

原文链接：

hello，大家好啊，今天给大家介绍如何在统信UOS 1060 上替换原有的开机音乐，正如之前我们所讲述的方法，需要通过ffmpeg命令首先将mp3格式或者mp4格式的文件转换为wav格式，然后进行替换。

今天的操作是一个示例，通过此示例的学习您可以替换对应位置的任何音乐，欢迎大家浏览分享转发。

1、将mp4格式文件转换为wav格式文件

• -i input.mp4：指定输入MP4文件的文件名。

• -vn：表示不要包含视频流，只提取音频。

• -acodec pcm_s16le：指定音频编码器为16位PCM（无损音频）。

• -ar 44100：指定采样率为44.1 kHz，这是CD音频的标准采样率。

• -ac 2：指定声道数为2，表示立体声。

2、将mp3格式文件转换为wav格式文件

• -i input.mp3：指定输入MP3文件的文件名。

• output.wav：指定输出WAV文件的文件名。

3、将文件desktop-login.wav拷贝到/usr/share/sounds/deepin/stereo目录下

uos@uos-PC:~/Desktop$ cd /usr/share/sounds/deepin/stereouos@uos-PC:/usr/share/sounds/deepin/stereo$ ls -ltr desktop-login.wav -rw-r--r-- 1 root root 1234878 5月 13 2020 desktop-login.wavuos@uos-PC:/usr/share/sounds/deepin/stereo$ uos@uos-PC:/usr/share/sounds/deepin/stereo$ sudo cp desktop-login.wav{,.bak}请输入密码:验证成功uos@uos-PC:/usr/share/sounds/deepin/stereo$ ls -ltr desktop-login.wav-rw-r--r-- 1 root root 1234878 5月 13 2020 desktop-login.wavuos@uos-PC:/usr/share/sounds/deepin/stereo$ ls -ltr desktop-login.wav*-rw-r--r-- 1 root root 1234878 5月 13 2020 desktop-login.wav-rw-r--r-- 1 root root 1234878 9月 26 16:09 desktop-login.wav.bakuos@uos-PC:/usr/share/sounds/deepin/stereo$ sudo cp ~/Desktop/desktop-login.wav ./uos@uos-PC:/usr/share/sounds/deepin/stereo$ ls -ltr desktop-login.wav*-rw-r--r-- 1 root root 1234878 9月 26 16:09 desktop-login.wav.bak-rw-r--r-- 1 root root 131150 9月 26 16:09 desktop-login.wavuos@uos-PC:/usr/share/sounds/deepin/stereo$

4、重启lightdm

uos@uos-PC:~/Desktop$ sudo systemctl restart lightdm

5、点击查看系统音效是否改变

6、重启电脑测试是否生效
