View Full Version : [SOLVED] Sound card not being detected
May 2nd, 2010, 03:09 AM
I have just upgraded to 10.04. Everything is working just fine. In fact i really like the transition to the latest firefox version.
But my sound card is not responding. I can not change the volume on my system. My speakers are working and there is sound. But i can't change the volume. Also even if my earphones are connected, the speakers keep working. Might have got into a mess at my workplace today.
How to resolve it?

When you say you cannot change volume, are you saying your volume control doesn't do anything or you don't have a volume control?

The volume control icon is present but it doesn't do anything. Also when i go to sounds from Preferences, it just says waiting for sound card to respond.

Try changing the volume in the Terminal

Can you post the output of these terminal commands for me please:
head -n 1 /proc/asound/card*/codec#*
Please post text output using code tags. Also helpful is the make/model of your PC/Laptop.

The output from the commands that you wanted me to execute are
root@blitzkreig:~# uname -a
Linux blitzkreig 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux
root@blitzkreig:~# aplay -l
**** List of PLAYBACK Hardware Devices ****

root@blitzkreig:~# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.
root@blitzkreig:~# head -n 1 /proc/asound/card*/codec#*
Hope that helps. And you can help me to sort out the problem.
Thanks a lot

What is the make/model of your PC/Laptop?

I'm using a Compaq NX6325 by HP. It is a 2006 model. Was working perfectly with 9.10.

If it was working with karmic it should work here. Have you tried alsamixer? Also try gnome-alsamixer (in the repo's if not installed) and make sure to enable all options in "Edit> Sound Card Properties". For alsamixer:
Press F6 to select the correct soundcard.
Press F3 to show playback levels. F4 selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels.
Go to "System>Preferences>Sound" and make sure the correct soundcard is default.
One more thing - have seen botched alsa installs latety. Try upgrading it referencing this post:

Thank you so much for walking me through this. I remember that even for 9.10 i had used alsamixer to sort out the sound once and so it was easy thereafter.
