KVM的客户机没有声音

黄色蚂蚁

KVM86版，64位的系统，客户机装的是XP SP3
HOST的声音正常的，但客户机没有声音
qemu-system-x86_64运行的时候出现如下错误：

搞了一个下午，都找不到解决方法，请高人指点一下，谢了

1. kvm -hda winxp.img -smp 2 -localtime -soundhw es1370 -M pc -m 512 -boot c

复制代码

上面是我启动kvm的参数，声音正常。

启动KVM:
%cat ./bin/kvm.sh
#!/bin/bash
if [ `pidof qemu-system-x86_64` ]; then
    echo "KVM is already running..."
    exit
fi
/usr/local/bin/qemu-system-x86_64  -m 256 -soundhw es1370 -hda /media/E/winxp.img -hdb /dev/sda7 -localtime -net nic -net user -nographic -daemonize -redir tcp:3389::3389 -boot c -k en-us &

连结KVM
%cat ./bin/xp.sh
rdesktop localhost:3389 -u sw2wolf -p 123 -g 1440x880 -D -r sound:remote -K

声音正常

问题解决了
是由于我在内核中编绎了4650显卡的HDMI声音模块
造成CARD 0是HDMI，真正用的声卡LIVE分配到CARD 1去了
造成ALSA的不正常
把HDMI的模块在内核中去掉就正常了
看资料说还可以用ALSA的工具修改默认声卡，但没试过
