Please, please don't apport-collect -p alsa-base foo (or apport-collect foo in 10.04 LTS) into a bug report that you didn't file unless a member of the audio dev team explicitly requests it. What we end up with are reports that start from the original reporter as "my laptop's internal mic doesn't work" and end with dozens of unrelated comments from other people along the lines of "my laptop's internal speakers are too loud".
Here's the gist: your symptoms may be eerily similar, but your audio hardware often is quite different, which means that resolving the original reporter's bug symptoms should only affect that reporter's hardware. Of course, if you have identical hardware, then your symptoms will be resolved in your own bug report, too. If you didn't file the original bug report, please just file a new one. Thanks for understanding.
