DONE: If alsa-lib and alsa-driver support it,
alsamixer now displays dB gain levels for all mixer controls.
TODO: Implement alsa-lib and alsa-driver parts.
Fixed unexpected abort of alsamixer when no playback or capture elements
are available. Also fixed the wrong use of temporary array in
displaying item name.
alsamixer shows all view names in the View: line so that user
can understand what it means. The currently used view is
shown with brackets and emphasized.
Improved the usability of alsamixer:
- the mute/unmute appears in a separate box below the volume bar
more obviously
- the capture switch appears below the volume bar, too
- the controls without volume doesn't show volume bars
- fixed bugs with all view mode
- fixed the calculation of volume bar size
- show left/right scrollable status
- code clean up
The volume bar and space sizes are recalculated at each time when
the view mode is changed. This will fix the problem when the view
with fewer volumes is switched to the view with more volumes.
It causes alsamixer to display 2 different views of the mixer controls.
One view shows only the "Playback" controls, the other view shows only
the "Capture" controls, with a hidden mode (Press F1, then Enter) to
show the old method of all controls together.
With ncurses 5.4 or later, it is necessary to have the
correct LC_CTYPE setting before calling initscr(). Otherwise, the line
drawing characters and boxes are not visible on Linux console in UTF-8 mode,
and that makes alsamixer totally unusable on such terminal.
- add a "Press Escape to quit" string to alsamixer's title, some uses
couldn't figure out how to exit the program (Debian Bug#178393).
- hide the cursor, which was missplaced and wasn't goodlooking anyway
(Debian Bug#81169).
- remove trailing spaces from amixer's output (Debian Bug#177518).
- don't ignore second -l/-L flags in aplay (Debian Bug#177521).
now capture volumes are displayed and controllable as independent
bars from playback volumes.
e.g. on emu10k1 you'll see both "AC97" and "AC97 Capture".
there is still a bug in handling of "Capture Volume" control.
