Question

注意：我要求关闭此问题，因为结果是Linux/Qemu特定问题。

我在Linux Mint 16笔记本电脑上的Qemu虚拟机中尝试Android x86 4.4-r2。安装成功。到目前为止，我最大的问题是声音。我已经尝试过来自Qemu的SB16，ES1370，AC97虚拟声卡型号，但我的虚拟机没有声音。这是Android 4.4-r2中的内容：

# alsa_actl init
Found hardware: "SB16" "CTL1745" "CTL1745" "" ""
Hardware is initialized using a generic method  #exit code is 22

我还尝试了EEEPC版本（4.0），ES1370，as suggested。同样的事情：没有声音。

虽然使用SB16驱动程序，但alsa_aplay /system/media/audio/ringtones/Sceptrum.ogg似乎有所作为，但我什么都没听到。

我有一台Windows虚拟机，我可以从中听到系统声音。因此，我绝对排除了Qemu的一个问题^（**）。

我也从question #11037254查找了建议，但没有一个有效。

任何人都能解释一下吗？

^（**） 嗯，事实上，并不完全排除！我刚刚注意到，到目前为止，我的GNU / Linux虚拟机都没有输出声音。只有我的Windows虚拟机可以，我不知道为什么会这样。

编辑：从Linux虚拟机中检测到硬件。

Answer 1

在Archlinux中，经常出现同样的问题。有几个声音引擎： gstreamer ， vlc 等。最常见的是 gstreamer 但如果我想要声音，我必须更改为 vlc 。

在Qemu（Linux Mint 16主机）
