View Full Version : [ubuntu] No sound after upgrading to 9.10

October 31st, 2009, 04:01 AM
I use optical audio for sound (whatever that series of numbers is...) and after upgrading to 9.10 I don't have any sound at all anymore. I'm using an Asus P5K3 Deluxe with integrated sound if that helps. If there are some log files or something I can post to help, please let me know.

Thank you!

I have a Dell Mini 10. The same thing with no sound happened to me after upgrade (of 9.10). Now the sound is working perfectly. I used this to fix the problem (Its very simple to do). Maybe the solution for your card is somewhat similar.


Quoted from the website:"

Follow these steps:
1.First you must find which model of sound card you use, so run this command:

cat /proc/asound/card0/codec#* | grep Codec

Note: You should obtain this:

Codec: Realtek ALC269
Codec: Silicon Image SiI1392 HDMI

This means that your soundcard is ALC269. If it is not ALC269, follow the instructions here. Otherwise, continue to step 2.

2.Open /etc/modprobe.d/alsa-base with the following command:

sudo nano /etc/modprobe.d/alsa-base.conf

3.Paste the following line at the end of the file:

options snd-hda-intel model=basic

Save the file and close it.

4.Go to System>Preferences>Sound>Hardware.
On the Profile drop down menu, select "Analog Stereo Output".
Make sure the Output Volume is set to 100% and close.

5.Reboot and now you can enjoy Karmic with sound:) "

The output of the terminal command came out "Analog Devices AD1988B" for me, so I don't think the rest of that tutorial would work since it is for intel sound cards. Thanks for the link anyway though.

Different board, same card, same problem.
