Package: hotkeys
Version: 0.5.7.4-0.1
Severity: normal
Tags: patch
I've implemnted support in hotkeys for using the alsa mixer. A patch is
attached. It's fairly complete, though I hardcoded -lasound in the
Makefiile, as I don't enjoy messing around with autoconf.
I chose to only enable alsa if the ALSAcontrol config file option, which
probably needs to be tuned for each system anyway, is filled in. Without
that it will continue doing the old-style OSS mixing, which doesn't seem
to affect the alsa volume at all.
Since the patch allows ALSAcontrol to be set to a list of controls,
which are all controlled at once, it fixes bug #305716. A useful tip for
laptops with separate speaker and headphone volumes: Have hotkeys
control them both, and use alsamixer to mute the headphones. Then when
you toggle the muting, the headphones will unmute, and the speaker will
mute, so you can switch between them like that.
