Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Intrepid Ibex. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

If it's still not working in Intrepid, please include the information requested from the "Reporting Sound Bugs" section of https://wiki.ubuntu.com/DebuggingSoundProblems as separate attachments.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!

I have this same problem in a Toshiba Satellite U200-SP7011. I muted the sounds in Windows XP, and now there seems to be no way to unmute it from Ubuntu. I am using Ubuntu 8.10.

I followed the instructions in https://wiki.ubuntu.com/DebuggingSoundProblems, and the utils_alsa-info scripts created the next link:

http://www.alsa-project.org/db/?f=f55111afcf0e4768bc2d57da1adc560330c8b21c

I am also attaching the output of the script and changed the status of the bug to New as Dimitrios suggested. Thanks in advance for your help.

Does it make a difference if you shut down *completely* so you do a cold boot
into Ubuntu rather than doing a warm reboot?

No it does not make a difference, the problem appears in both cases when doing a cold boot or a warm reboot.
