Audio Stopped Working

[Gene Bray]

In approx. the last 7-10 days, audio on my computer stopped working (audio has worked fine since installing 12.04 LTS) and I have not been able to get it working since. Sound works fine in Windows 7. OS is Ubuntu 12.04 LTS patched current. Hardware platform is: HP Pavilion dv6t-6c00 CTO Entertainment Notebook PC, Product number (P/N): A1U60AV.

I performed a complete uninstall of all applications I could tell have a direct link to audio that were recently installed/undated (VLC) and rebooted. Did not fix the problem so reinstalled VLC. Used synaptic to completely uninstall all pulse audio files, rebooted, and reinstalled pulseaudio. No help. While I have been using Linux for a while, I still consider myself a noob. Will glad help anyway I can troubleshooting this problem.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1099237/+editstatus and add the package name in the text box next to the word Package.

[This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.]

[Gene Bray (genebray)]

This is a guess as to the proper package. I followed the troubleshooting information and cannot id a specific package.

aplay /usr/share/sounds/alsa/Front_Center.wav results in nothing from the speakers. I verified the wav files is present in this path. Running as root nets no sound.

The only other user on this computer has no sound either.

The OS is 64-bit Ubuntu 12.04 LTS patched current.

See the three attached files for diagnostic output test results.

Please run the command "apport-collect 1099237" in a terminal, so we can get some more information about your hardware.

[Gene Bray (genebray)]

Will do. Results posted shortly.

Latest patches, available this morning in the US for pulse audio, did not affect this issue. Should I run the "apport-collect 1099237" command again to provide a current view of the system?

[Gene Bray (genebray)]

There are 4 speakers on the computer and no separate head phone volume
control. The function keys on the computer serve a dual purpose.
Pressing an "fn" key allows traditional function key use of the function
keys. Their default is to provide various hardware controls. F9 is
down volume, F10 is up, and F11 disables sound when pressed without the
"fn" key pressed along with the appropriate function key.

Attached is the output from pulse audio testing.

I followed the directions in the link. Played a wav file (aplay /usr/share/sounds/alsa/Front_Center.wav) and then completed the directions. There was no sound from the system.

[Gene Bray (genebray)]

Sound started working late yesterday. Only changes to the system were installing updates/patches that came out this week and last night I removed numerous foreign language fonts that I never use. The only place I know I can find a history of SW installs/removal is in the software center. I'll try to local the assocated log file and post if will assist.

[Gene Bray (genebray)]

Found the log file. It is attached.
