[Bug 248829] New: Double sound volume setting with hotkey-setup on IBM Thinkpad T42
https://bugzilla.novell.com/show_bug.cgi?id=248829 Summary: Double sound volume setting with hotkey-setup on IBM Thinkpad T42 Product: openSUSE 10.2 Version: Final Platform: x86 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: lenz@grimmer.com QAContact: qa@suse.de Thanks a lot for providing hotkey-setup, which generally works very well on my Thinkpad and maps many buttons to the correct function. However, with regards to the sound volume buttons there is the following problem: on my Thinkpad model (not sure about others), the Volume up/down keys already control the hardware volume control, which is always enabled and is OS independent. So when I now press these keys to change the volume, the sound level is adjusted at two different places at the same time: the hardware volume control and the ALSA sound driver, making it hard to change the volume on a fine-grained level. You can observe this effect by starting the "tpb" tool and having its OSD enabled. Pressing the volume buttons will then result in two volume indicators being displayed, which both change when the keys are pressed (but at different levels). As it's probably not possible to disable the hardware volume control when pressing these keys, it would be helpful if one could at least disable the changing of the volume in the ALSA sound mixer. In other words: it should be possible to disable the mapping of the volume keys in thinkpad-keys. The same applies for the sound mute key as well, by the way - but here the effect is less annoying. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I have been looking into that and could only cook some dirty hack. Let's discuss here how to proceed. The hack is that I can use ibm-acpi to modify the volume (I was not able to do this using /dev/nvram). Thus, whenever we read a volume up/down event from /dev/nvram we could (a) send an the corresponding events via uinput and (b) reset the volume to the level it was before using ibm-acpi That hack is really dirty and I really do not like it much. Especially, it will break the support to control the volume without having some mixer running which does the ALSA stuff. As another approach we could tell users to disable the mappings (volume up/down event -> GNOME Mixer / KDE Mixer) GNOME and KDE. That solution would not be a hack but it probably will eliminate the OSD and requires an user action to be changes. By default we would have the behavior as it is today on FACTORY. What do you think? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I agree your first suggestion is a bit hackish and confusing. As tpb provides its own OSD display for the volume level of the hardware mixer, I'd be happy to have an option to disable the mapping of the volume buttons with the software mixer. Thanks! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Agreed. For future releases of the Linux kernel it looks that ibm-acpi will ship with a ALSA mixer anyway. Work is in progress -- not sure if it will become part of OS10.3. Until then I'll go forward and implement the configuration option for hotkey-setup. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
