[SOLVED]no sound in both headphone and speaker after update (alsa)

XuYimin · 2014-01-15 04:59:16

No sound after update. But, I can hear sound in headphone after install pulseaudio, while there is no sound in speaker (after plugging out headphone). I have tried some methods in related wiki articles, such as alsa and pulseaudio, but not works.
My enviroment is arch64, kde. I have installed lib32-alsa-plugins lib32-libpulse lib32-openal.
Anything others I can do? Thanks for advance.

Here is the output:

first Have a look at alsamixer to check if something is mute (automute )

edit
or try

amixer set -c 0 Master 25 unmute
amixer set -c 0 PCM 25 unmute

XuYimin, can you please give more info on what you mean by "update (alsa)"? There is no "alsa" package in Arch as alsa & it's modules are part of the (linux) kernel.

As you have already gone into alsamixer to ensure the appropriate channels are unmuted & set at the desired level, have you also gone into your KDE systems settings -> Multimedia -> Audio and Video Settings & rechecked your settings?

sorry，it's really misleading in my words.what i want to say is 'no sound after update, and the sound system is alsa.'
i'm sure the approiate channels are unmuted. in the Video Setting, I tested all sound cards in the list, But i can't hear sound.

The sound device works well after updated just now, the problem is solved.
