Under Linux these buttons do nothing. The mute button is always lit even when sound is coming out. The volume control buttons do not adjust volume. ====================================================================== ---------------------------------------------------------------------- tiwai - 11-09-04 10:35 ---------------------------------------------------------------------- Usually these buttons are controlled over ACPI. In some cases, you can get a key event in X server, then you can configure the window manager to do the right thing. Anyway, this is not a bug or a missing feature of the sound driver. ---------------------------------------------------------------------- Mark Knecht - 11-09-04 16:13 ---------------------------------------------------------------------- This was not filed as a bug. It was filed as a feature request. Please do not be so dismissive. What did you spend? Maybe 3 seconds and then blew it off? Under Windows the buttons control volume. Pushing the buttons raises or lowers volume in the applications. you can see the volume controls go up and down. Why should Linux *not* work this way? I am requesting that Alsa consider how to be more user friendly. I am not filing a bug report. If they are already handled under ACPI (which I do not use on my laptop as it causes kernel timing problems) then please simply state that Alsa already handles this. However, I do not beleive that these specific buttons are handled by ACPI, but that's just my guess. ---------------------------------------------------------------------- tiwai - 11-09-04 16:57 ---------------------------------------------------------------------- Calm down, this has *nothing* to do with ALSA although the buttons are printed as volume up/down. There is *no* hardware connection between buttons and the sound chip in your case. Thus, there is nothing the sound driver can do for this directly. To support this feature, the ACPI event must be handled by a certain user space program such as the window manager (or desktop system). Windows works because it grabs the ACPI event and processes it properly. Linux could handle this but the current system doesn't care it. ---------------------------------------------------------------------- Mark Knecht - 11-09-04 17:49 ---------------------------------------------------------------------- There's no point discussing this. Bye. ---------------------------------------------------------------------- jdthood - 03-19-05 15:33 ---------------------------------------------------------------------- This can be closed.
