no sound after upgrade to Gutsy Gibbon

Have you already double clicked on the top right loudspaeker icon to check devices...?
Are they all unmuted...?
Thank you

First, try to reinstall alsa

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get --reinstall install alsa

give your user password when requested, you don't see nothing when you type it, then press enter.

Then try this: https://help.ubuntu.com/community/HowToSetupSoundCards

Please give us some feedback

Thank you

I'll try it this afternoon 'cause I'm on my work now. Thanks for this fast reaction!

I did as you sad. No changes. just for a split of a second sound. Then the running program closes immediately.
Thanks

I've got some more information:

dieter@Cepheus:~$ cat /proc/asound/cards

 0 [VT82xx ]: HDA-Intel - HDA VIA VT82xx

                      HDA VIA VT82xx at 0xfbffc000 irq 22

 1 [io2 ]: USB-Audio - io|2

                      Alesis io|2 at usb-0000:00:10.4-2.1, full speed

dieter@Cepheus:~$ asoundconf list

Names of available sound cards:

VT82xx

io2

That io2-card is the problem. It's an externel usb-soundcard from Alesis

Please try to investigate if your Ubuntu is getting some system or error messages back to you.

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

tail -F /var/log/syslog

give your user password when requested, you don't see nothing when you type it, then press enter.

Don't close terminal window and try to play something, look for some interesting audio related system messages.

Hope this help

Hi,

No systemerrors!
Terminal looks like:

In both cases I tried to run Rhythmbox musicplayer. I saw the titles of the CD and for a very short moment even the CD inlay.

Have a nice WE

I found on internet:

>>May 22 11:11:46 nomade kernel: 5:2:1: cannot get freq at ep 0x82

And that did the trick: it works! So what now: should it stay like it is
or can I help you (I put USB list in copy) to debug it to have a clean
driver?

I don't find sound/usb/usbaudio.c

while running ubuntu 7.10 I unplug the external usb soundcard. Then I start Rhythmbox player. The sound is comming from the internal souncard. While playing I connect the extarnal usb-card. And see what happens: the next song on de CD comes from the external sound card! By doing nothing. I can provoke it over and over. But I dont see the usb in the ALSA mixer!
