*** This bug is a duplicate of bug 39098 *** I did not do anything to trigger this behaviour. Out-of-the box (more- or-less, as my notebook was installed with the dapper development branch a long time ago, and is constantly updated), I already had the weird behaviour, that the Thinkpad buttons control both the thinkpad mixer and the soundcard mixer.
Just recently, the fact that the soundcard mixer assignments swapped, I noticed this behaviour. Your proposal sounds reasonable, although I would wish for a checkbox in some [gnome|kde|xfce|whatever]-button-management-daemon-control-center to enable or disable the link between the thinkpad mixer and the soundcard mixer. Because (now it gets even more tricky) when one of my soundcard mixers (master and PCM) get raised above ca. 70-80%, the sound quality deteriorates rapidly (analog clipping, overdriving,...). But the thinkpad hardware mixer can be set to maximum w/o sound deterioration. So I'd like to control them independently. A friend of mine has an old Acer laptop with a real analog volume control, it's just a variable resistor w/o software control. I would wish for my hardware thinkpad volume buttons to be the same, with the extra function of a working on-screen-display, and an _optional_ software control. -- ibm-acpi volume control unpredictable https://launchpad.net/bugs/42886 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
