I wanted alsamixer to support transparency. Took a bit of googling and a wee bit of hacking, but nothing too hard. This guide probably relevant only to alsa-utils 1.0.21+.
Know your system
Make sure libncurses (development version with headers etc) is installed.
Run
cat /proc/asound/version. This will tell you your alsa-utils version.
The dirty work
Download the source for your version of alsa-utils. Ubuntu users can find their source code at Launchpad:
https://launchpad.net/ubuntu/+source/alsa-utils
Extract it, go into
alsa-utils*/alsamixer/. Edit colors.c. Look for the section
void init_colors(int use_color). For each line that starts with
init_pair( and has
COLOR_BLACK as the second colour, change
COLOR_BLACK to
-1. Eg:
Code:
init_pair(1, COLOR_CYAN, COLOR_BLACK);
becomes
Code:
init_pair(1, COLOR_CYAN, -1);
Save
colors.c. Run
make. Copy the resulting
alsamixer to
/usr/local/bin.
