[SOLVED] No sound after massive upgrade

eherranzr · 2012-05-14 18:09:14

Hello,

I'm just writing to ask for some information about my problem. Recently I upgraded my ArchLinux system after a while without doing it.
My surprise came when, after rebooting my system is without sound. No sound anywhere. Both the speakers and the volume are turned up at the maximun and there's still no sound.
I would appreciate any information you could give me to solve this problem which is killing me.
Also say that before the upgrade the sound was working perfectly.
Here's my rc.conf file:

#
# /etc/rc.conf - Main Configuration for Arch Linux

One sound-related thing that changed recently is pulseaudio getting updated to version 2 - are you using it?

Check if the sound modules are being loaded

lsmod | grep snd

I don't really know if I'm using it, I'm a bit lost about that.
In preferences it seems like I use Gstreamer but I don't know if that's what you're saying

This is what lsmod | grep snd tells:

snd_hda_intel          23989  5

Are you in the audio group?

$ groups

Try to follow the wiki as closely as possible. Install alsa-utils, run "alsamixer" and make sure no channels are muted (no "MM").

$ speaker-test -c 2

My sound card stopped working today after I updated. I was surprised because my soundcard always worked before. My music player (audacious) said something like "No audio device available".

I had to reboot 2 times. After that, my sound card worked again. I don't know why.

I don't know if you have the same problem as me, but we both had a similar problem on the same day doing the same thing (working sound card -> update -> no sound). Maybe it's just a coincidence?

Sure, I'm in the audio grup:

This is what I tried the first but everything seems okey:

Tried it also, but no sound in the speakers.

What a shame but that was not the solution, my computer has been rebooted more than twice since then and still no sound

DSpider · 2012-05-15 12:24:56

Do you dual boot with something? Something that you can test the sound with. A "live" Linux distribution should also work.

Because this means that it works:

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)

 1 - Front Right

You should be hearing pink noise (static). It's probably a physical problem. Audio jack not being plugged all the way, volume not turned up. That kind of thing.

eherranzr · 2012-05-15 12:32:49

What a weird thing, after the upgrading I didn't touch the jack.
Now I just unplugged it and plugged it again and it works.
What a stupid solution and what a weird problem.

Thanks, you solved the problem!

DSpider · 2012-05-15 12:51:25

That's great! Don't forget to mark it as solved.

A few plausible scenarios:

- The audio jack is getting old, worn out, or it may need resoldering.
- You tripped over a wire when you went to the bathroom.
- Something fell on it from the desk.
- The cat chewed on it.
- Someone did some cleaning around the desk.
- You did some work around the cables recently (USB stick, Ethernet cable, etc) and accidentally moved one.
