Video, Flash and system have no sound

[ubby]

I am working with Ubuntu 8.10 but have no system sound and also no sound when I play a video and Flash.
Some video players crash because the can not find a sound plugin.

When I close Pulse audio I can play a video with some players (with sound) and play music with only Gxine.
But this will not solve the problem.
I think this is a very important bug to be solved if there are more people with the same problem.

Can you read this page https://wiki.ubuntu.com/DebuggingSoundProblems in order to see what may be your problem.
If this page can not solve your problem, please post a comment and set the status of this bug report to new.
Can you give the result of cat /proc/asound/cards

The sound did work fine with Ubuntu 7.10 (my first Ubuntu) but with the release of Ubuntu 8.04 the sound didn't work anymore.
I think this problem is caused by Pulse audio because in Ubuntu 8.04 Pulse audio was implemented for the first time.

desktop:~$ cat /proc/asound/cards
 0 [HDMI ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xf5010000 irq 17
 1 [DMX6Fire ]: ICE1712 - TerraTec DMX6Fire

Please, read https://wiki.ubuntu.com/DebuggingSoundProblems, the instructions on this page may solve your problem.

With Ubuntu 8.04 I have done all troubleshooting and with help from the Dutch forum but it didn't solve the problem.
Also if there is a solution with troubleshooting than it is still a bug because the sound have to work out of the box.

After I did this (https://wiki.ubuntu.com/DebuggingSoundProblems) troubleshooting the sound still not work.

When I test the sound in Preferences > Sound I get the following message:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect stream: Invalid argument

DId you try to uninstall pulseaudio to see if the problem comes from it?

[ubby (kostas-sytske)]

With Ubuntu 8.04 I have tried to uninstall it etc. but with Ubuntu 8.10 I close Pulse audio in the System monitor.

[arno_b (arno.b)]

To stop pulseaudio run:
sudo /etc/init.d/pulseaudio stop

Ok, thank you.

I have the problem from the moment that Ubuntu use Pulse audio.
With Ubuntu 7.10 I had no sound problems.

[arno_b (arno.b)]

Maybe it is a regression of the linux kernel. Please, test without pulseaudio (uninstall or stop it) and tell us if it works with alsa, esd or oss.

I had stop Pulse audio and now the sound testing works with the setup in the picture:

But I still do not have sound with the login and Flash.

So set to the pulseaudio package.
