在树莓派B+上编译使用ekho的问题

Question

我在树莓派一代B+（raspbian系统）上编译ekho，按照官方的文档安装，安装完后，执行命令ekho “hello 123”

提示：

pi@raspberrypi ~/ekho-6.3 $ ekho ¨hello 123¨
pa_simple_new() failed: Connection refused
pa_sample_spec(format=3,rate=16000,channels=ch=1)
Fail to init audio stream.
Fail to init sound.

@黄冠能  能帮忙看看是什么问题么？

以下是部分安装过程：

Answer 1

我使用aplay命令播放wav文件是有声音的，使用espeak也是有声音的

Answer 2

我使用sudo apt-get install pulseaudio ，安装完后使用ekho “hello”，能播放声音了，但是声音一直是杂音，听不到内容

Answer 3

好吧，安装了pulseaudio后，所有声音都有问题了，只有再折腾折腾了

Answer 4

ekho 123 -o demo.wav && aplay demo.wav播放的声音是否正常？如果不正常，能否把demo.wav发我邮箱（hgneng at 163 com）?

Answer 5

回复
demo.wav文件是正常的，可以听清楚，就是有点杂音。看来还是pulseaudio的原因，现在wav文件都播放不正常了

Answer 6

可能
raspbian系统没有使用pulseaudio作为声音服务程序，怎样启用这个声音服务程序我不是很熟悉，暂时没有建议。你试试./ekho 123 -o demo.wav，然后play demo.wav看有没有声音。
