No sound on dual boot 64-bit Ubuntu12.04
After a few days of trying different things I can't get the sound to work in 12.04.
This is a Dual Boot set up -- 64-bit Ubuntu 12.04 & 64-bit Windows 7, Sound works on Windows 7. Sound worked when 12.04 was first installed 12.04 was reinstalled a couple times while resolving some boot issues (grub/grub2) Now the sound won't work. AlsaMixer seems OK. (see attached pic) Alsa Information Script is here: http://www.alsa-project.org/db/?f=7e...d7c8a1879a3ce4 I have tried to apply suggestions from these posts. https://help.ubuntu.com/community/SoundTroubleshooting/ https://help.ubuntu.com/community/So...otingProcedure http://www.unixmen.com/2012003-howto...lem-on-ubuntu/ I am missing something, probably simple. If you see what that is, please help. |
Too much there for me to read atm.
Go through from square 1. Have you a /dev/dsp0? When you run alsamixer, what do you see? What are you using to set up sound? |

I have started from what I thought was square 1 several times. Now i'm not even sure where square 1 is anymore.
There is a screen shot of what AlsaMixer shows attached. It looks normal to me. When I look at the Alsa Information Script www.alsa-project.org/db/?f=7e...d7c8a1879a3ce4 it seems to me that things should be working. Here is a small part of what it shows. Code:

Square 1 is really where you know nothing and just start making basic sensible tests.
/dev/dsp is for OSS /dev/snd/* is for alsa. Agreed alsamixer looks OK, except for microphone, maybe.I would open it out (all devices) and make sure everything is at at least half volume as the hda intel structure is like a spaghetti junction of hardware blocks all interconnected, and it's possible to do things several ways. Alsa is recognizing 2 cards - an internal hda_intel and an external usb audio device. Which are you using? |
The external usb device is a Webcam. I have disconnected it & will reconnect after sound is working.
Now I am going to start over at square 1. I'll update when done. Somehow I did not notice that, Thank you for taking the time to notice. |
Sound is working now.
It turned out to be a simple fix. Here is what I did: Opened PulseAudio Volume Control Code:
pavucontrol PHP Code:
Code:
alsamixer PHP Code:
