Bug Description

Binary package hint: pulseaudio

Booting off a USB stick with Ubuntu Lucid 10.04 from 3/22/2010 daily build. There is no sound from anywhere. Upon checking the Sound settings from System->Preferences->Sound, the output device listed is "Dummy Output Stereo". When running Ubuntu 9.10 on my desktop(HP Pavilion a6430f), the output device listed is "Internal Audio Analog Stereo Stereo". Apparently something failed to recognize my audio setup in Lucid. I obtained the follwoing information from reading teh Sound Problems FAQ:

lspci | grep "Audio device"
00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)

1. lsb_release -rd
Description: Ubuntu lucid (development branch)
Release: 10.04
3. I expect Lucid to recognize my hardware setup and provide full sound.
4. This particular build of Lucid does not.

Your audio devices *are* recognized; see your Card0.Amixer.values.txt and Card0.Codecs.codec.0.txt. Furthermore, PA only drops to the null sink/source when something has already grabbed the sound device. Can you obtain a verbose log (https://wiki.ubuntu.com/PulseAudio/Log) to verify?

I followed the instructions given at the web site and have attached the verbose log file generated.

You didn't mention whether audio was audible (e.g., Rhythmbox) while you were running PA with verbose logging.

I was going to run this procedure once again, making sure that I was playing audio from Rhythmbox while generating the log, and the sound came back. If, as you suggested, something "else" grabbed the sound card it apparently let go of it. I am sure that if I reboot the sound will go away again. I will try that and report. I had tried several reboots, all with no sound.

I have now rebooted several times and each time I have sound. However, several things that were originally working when I first booted in Lucid this morning no loner work: the keyboard voulme up/down and mute no longer work. If I select System->Preferences->Sound, I receive a response: "waiting for sound system to respond" and I never receive any additional response. I am happy that I now get sound, but all these things work on Karmic 9.10. I am thankful that I am demoing Lucid on USB stick, so I do not lose Karmic. I verified the md5sum for the image I downloaded.

I have now booted off a USB stick with Lucid build from today 3/23/2010 17:21pm, and when I boot there is no sound. Selecting System->Preferences->Sound->Hardware shows Dummy Output/Stereo" as yesterday. I started application Rhythmbox and was playing songs from my library. There was no sound audible, either from the speakers or from my headphones. I then started the procedure to produce another verbose log. Entering the first coimmand line "echo autospawn..." had no effect on the sound. When I entered the second command "killall audiopulse", the sound came back. However, Select Sound still shows "Dummy Output/Stereo" but the keyboard buttons (mute, volume up/down) work. At first Select Sound produced the warning that it was waiting for the sound system to respond but then it does after a few minutes.

Another data point. I booted off both a DVD and USB stick with Lucid 10.04 daily build 3/25/2010 8:13am. In both cases, there is no sound on my system (HP Pavillion a6430f) 64-bit) from anywhere(speakers and/or headphone). The up/down volume buttons provide feed back that pressing the buttons is responding, but there is still no sound. When I get the sound restored (first two steps in obtaing verbose log), System->Preferences->Sound does not respond nor do the up/down volume and mute buttons have any effect on the sound.
I booted the DVD Live on my laptop CQ60-615DX, also a 64-bit machine, and there was no sound. The sound card information obtained from lspci}grep Audio: 00:1b.0 Audio device Intel Corporation 82801I (ICH9 Family) HD Audio controller (rev 03). I was able to restore audio as described for the other cases. Maybe the problem lies in the 64-bit lucid version. Next time I will burn a non-64 bit Live CD and see what happens.

I burned a live DVD using 386 image from 3/25/2010 daily build, and the same sypmtons of no sound still are there on my system. I was able to restore audio by the same means as in the other cases. After audio is restored, hitting the mute up/down volume keyboard buutons causes the Gnome settings appliaction to crash with an assert, but the system will not let me report this crash. The crash causes the top/bottom panels to loses their current color, and icons are different.

Yey! Just tried build from 29.3.2010 and solved this issue. :-)
Simply by killing PulseAudio and starting it again, sound showed up :-)
(pulseaudio -k && pulseaudio)

--solved--

Sorry to report but the sound problem still remains on my system using today's build (3/29/2010). I am happy that it works for you now.
