声音失真

声音失真

早上好。

今天我正在玩 sunvox,并且(可能在那之后)声音在许多应用程序中变得相当或非常失真。

谢谢。

添加:

如果必须的话:

ben@pav:~$ sudo alsa reload
[sudo] password for ben: 
/sbin/alsa: Warning: Processes using sound devices: 2175(pulseaudio).

声音在 alsamixer 中被调到中等级别。关闭 pulseaudio 后,我完全听不到声音了。

一些附加信息:

正在做

sudo apt-get purge pulseaudio gstreamer0.10-pulseaudio

sudo apt-get install alsa-utils gstreamer0.10-x

什么也没给。gstreamer-properties我可以看到在那里和sound菜单元素中输出设备。

答案1

在这种情况下,你会使用甚高频液晶?VLC 自带编解码器,可能会与其他编解码器冲突。请尝试卸载 VLC 并重试。
