alsa声卡的问题[部分已解决]

health_kxy

晚上看一个东西，因为怕吵，然后用alsamixer把声音给mute了。
第二天，打开机器后，声音再也出不来了。
用重新编译内核，把alsa弄到核心，弄成模块。死活出不了声音。alsamixer检查声音是打开的
。播放软件也不报错。但是就是没声音。
大家是否遇到过类似的事情呢？

define

声音是不是最小啊?

不是阿，我都弄到出现红色的了。主要是原来好好的。我用alsamixer静音，然后玩了下，后面安装了什么忘记了。好像没有安装什么。然后关机。第二天，打开机器，什么错误也没有提示。声音就没有了。用alsamixer调整没有用处。郁闷ing.....

重新
emerge -av alsa-driver试试看

我弄过了,编译成模块,编译进核心,都不行.

顶一下,我折腾了好几天了,谁能帮帮我吗?

n多天的实验,编译进内核,模块,编译成模块还出现错误,声卡模块进不来.
今天我不启动/etc/init.d/alsasound这个东西.声音就好了.太奇怪了.

health_kxy

只要我启动过alsasound声音就没有了.

alsasound is the daemon who save/restore your alsa mixer settings when starting or shutting down. If your soundcard works correctly without it, then just disable it. But It would be quite strange that you could have your alsa mixer settings save/restore without alsasound daemon.
