同样情况

音频输出切换BUG已经出现一个月有余，仍未解决，不知道该说什么好，挺心累的。

同样的问题.

内置耳机也没有声音. 1002版一切正常. 升级到1003后就出现了问题. 

这是一个非常低级的臭虫.  满心期待20.1能够解决这个问题, 结果很令人失望. 其实对20.1的唯一期待是消除这个臭虫.

我觉着深度目前还没有抓在重点.  对于影响功能的问题, 深度应该尽全力第一时间解决. 而不是让非常影响用户体验的问题久拖不决.

同样的机器过去五年运行Gentoo, 多次升级, 从未有过声音输出问题. 转到深度不到半年, 这种低级的问题就是出现了.

牢骚话说了一大堆. 问题还是要解决. 目前暂时用外接USB声卡代替机内声卡.

目前机器升级到20.1 (1010)版, 运行 5.8内核. 启动是系统日志, 记录了出错信息如下:

观察到一个现象. 登录后, 声卡清单在15秒以后才出现. 这个符合系统日志的记录, Pusleaudio无法一次加载成功.

内置声卡文件的权限是root用户和audio组有读写. 将用户加入audio组, 重新登录, 但问题依然存在.

问题可能出在cgroup权限上.  系统日志记载的信息:

作为排查问题的一步, 以root用户, 运行以下命令, 内置声卡耳机输出, 可以听到声音(随机的噪声. 注意声音很大, 不用把耳机太靠近耳朵).

cat /dev/urandom | aplay

作为用户, 同样的命令则无法听到任何声音.

由此可以得出一个结论, 问题出在用户权限上. 这也是无法改变声音输出的原因.  目前还在查找哪些文件的权限导致这个问题.

希望深度的同仁不要在旁边坐着看, 搭把手, 帮一下忙, 早点把这个恼人的问题解决.

不好意思, 恢复太长, 论坛限制字数, 分成几个短贴.

也因此发现这个论坛的一个问题. 当字数超过限制时, 没有任何提示, 仅仅是无法发帖.

这个框框本身不检测字数，提交后才检测，2333

1003电脑无声，还可以用蓝牙勉强有声音。

1010后，蓝牙也哑了，彻底无声了。

商店中 下载图一软件；

按照图2方式设置，蓝牙可以有声音。

内置耳机输出现在可以听到声音了.

用户必须是在加到audio组里. 加到audio组里后, 需要重新登录.

耳机插线需要拔出, 重新插入. 当耳机线插入时, 深度系统会自动转到耳机输出.

有时候耳机输出可能是静音的. 运行 alsamixer, 按F6选第一声卡, 如果耳机栏显示MM, 则耳机输出当前被静音了. 按m解除静音. 

蓝牙耳机依然无法正常工作.
