I understand what you mean. This bug report is in fact two bug reports joint together as one. On one hand we have the feature (as Matthew East decribed it) of having different stepsizes for up and down in the software mixer. And on the other hand we have the inappropiate combination of hardware mixer and software mixer volume changing when using the thinkpad volume buttons.
I disagree with Paul Sladens descission to mark bug #42886 as a duplicate of this bug. The problems addressed are different. -- thinkpad: volume button weighting https://launchpad.net/bugs/39098 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
