==========================================================================
-NOTE1: look into "config.h.in" to set some options as needed;
-
-NOTE2: If the system is on "ALSA's OSS emulation" and the app didn't run OK,
- remove the package and re-create it with those procedures:
-
- 'cat /proc/asound/oss/sndstat' and search the "Mixers" section.
- locate the desired 'mixer number' and then modify file "config.h.in",
- at "DEFAULT_MIXER_DEVICE" parameter. Then, re-create the package.
-
- Eg: if desired mixer is "2", modify "config.h.in" as below:
-
- DEFAULT_MIXER_DEVICE "/dev/mixer"
- ( to )
- DEFAULT_MIXER_DEVICE "/dev/mixer2"
+
+NOTE: The hacks/mods are for "ALSA's OSS emulation" in ALSA systems.
+
+NOTE2: There are two 'mod' files: "config.h.in.mod" and "volume.app.c.mod".
+ If you want to use them, simple rename them to each "original filename"
+ (remove ".mod" on filename).
+
+ "volume.app.c.mod" is a hack to fix the mute/unmute problem
+ for ALSA systems. (It uses "amixer" command as background).
+
+ "config.h.in.mod" is just a covenience to set some parameters.
+ eg: If is notified that the app is not running on the right mixer
+ (more than 1 soundcard), you may try to set the default mixer
+ before creating the package!
+
+ 'cat /proc/asound/oss/sndstat' and search the "Mixers" section.
+ locate the desired 'mixer number' and then modify file
+ "config.h.in.mod" at "DEFAULT_MIXER_DEVICE" parameter.
+
+ Eg2: if desired mixer is "2", modify "config.h.in.mod" as below:
+
+ DEFAULT_MIXER_DEVICE "/dev/mixer"
+ ( to )
+ DEFAULT_MIXER_DEVICE "/dev/mixer2"
+
+ Again, do not forget to rename the file "config.h.in.mod" to
+ "config.h.in" before creating the package.
