Qemu（Linux Mint 16主机）下基于Linux的虚拟机没有声音

Question

注意：我要求关闭此问题，因为它原来是 Linux/Qemu 特定问题。

我正在 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。我尝试过 Qemu 的 SB16、ES1370、AC97 虚拟声卡型号，但我的虚拟机没有声音。这是我在 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

我也尝试过 EEEPC 版本 (4.0)，带有 ES1370，as suggested。同样的事情：没有声音。

虽然使用 SB16 驱动程序，alsa_aplay /system/media/audio/ringtones/Sceptrum.ogg 似乎在播放一些东西，但我什么也没听到。

我有一个可以听到系统声音的 Windows 虚拟机。所以它绝对排除了我对 Qemu 的问题^(**)。

我还查找了来自 question #11037254 的建议，但都没有奏效。

谁能解释一下？

^(**)嗯，其实也不能完全排除！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。

EDIT：检测到硬件，来自 Linux 虚拟机。

Answer 1

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