FOSS Mixer

FOSS Mixer is mixer application for FreeBSD with OSS audio backend to set soundcard parameters. Mixer can be use to control audio levels, set recording source, and it includes white noise generator for testing the audio output. It is pretty much what mixer(8) does.

FOSS Mixer supports only FreeBSD, there is no way to get it to work on other systems.

User interface

There is various knobs for controlling the mixers, most notably knob for changing the mixer on upper right corner, and recording source selector on the upper left corner. Rest of the knobs and sliders should be clear what they are for. Each control has little green light nearby which lights if that control is supported by the mixer currently selected. When the light is yellow, it indicates currently selected recording source.

If Bass and Treble controls are disabled (the green led is off), try setting:

hint.pcm.0.eq="1"
hint.pcm.1.eq="1"

in /boot/device.hints. Check the right pcm device numbers in your system from /dev/sndstat.

White noise generator is useful to test if selected audio output works. Please note that audio level of the noise can be quite loud. Roll the Noise Vol down before switching the noise on, especially if you are using headphones!

Compilation

Go to apps directory in package root, and run ./build.sh fossmixer to distribute needed files to package's root directory. After that, go back to .. and run ./configure and gmake, then start or install the application.

Example steps:

$ cd apps
$ ./build.sh fossmixer
$ cd ..

To try app without installing it:

$ ./configure --prefix=`pwd` \
              --enable-debug \
              --enable-safemem \
              --disable-extended \
              --disable-color \
              --disable-menu \
              --disable-coords \
              --disable-draw \
              --disable-bob \
              --disable-math \
              --disable-remote \
              --disable-image \
              --with-libiconv=/where/is/your/libiconv \
              --with-libintl=/where/is/your/libintl
$ gmake
$ ./fossmixer.debug

Or, to install fossmixer:

$ ./configure --prefix=/install/root/for/app \
              --enable-native \
              --enable-safemem \
              --disable-extended \
              --disable-color \
              --disable-menu \
              --disable-coords \
              --disable-draw \
              --disable-bob \
              --disable-math \
              --disable-remote \
              --disable-image \
              --with-libiconv=/where/is/your/libiconv \
              --with-libintl=/where/is/your/libintl
$ gmake
$ gmake install
$ /install/root/for/app/bin/fossmixer

Try setting fossmixer.widget.fontFace to Acme-Regular.ttf or Antonio-Regular.ttf font from Google in fossmixer.res, they look very nice with FOSS Mixer, much better than default Noto font.
