This is actually even worse: on thinkpad T60 (but I guess on some other models as well), volume buttons are hardwired to control the volume otherwise inaccessible through normal sound drivers - the one you could look at with:
$ cat /proc/acpi/ibm/volume level: 14 mute: off commands: up, down, mute commands: level <level> (<level> is 0-15) This one has nothing to do with the devices alsa reports because there is still no alsa driver for it. the audiochip you control with alsa plays into this other device which only provides this extra volume control. I have no idea what's the reason for this design. So it is incorrect to let these buttons emit the same codes as normal volume control keys on "internet keyboards", which are then mapped to control the volume of Master or PCM strip of the alsa device, because what you get then is that each keypress changes the volume twice (on alsa device and hardwired) and the steps are too large. Also if you use external keyboard with volume keys, those will work correctly (only control the volume of selected channel of alsa device) but inconsistently with hardware buttons. The hardware buttons should really generate some altogether different scancode or event which should be then mapped to reading and displaying the status of /proc/acpi/ibm/volume and NOT of the alsa device. -- thinkpad volume keys control microphone - gutsy https://bugs.launchpad.net/bugs/136287 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
