|
||||
==========================================================================
|
||||
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:
|
||||
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",
|
||||
at "DEFAULT_MIXER_DEVICE" parameter. Then, re-create the package.
|
||||
locate the desired 'mixer number' and then modify file
|
||||
"config.h.in.mod" at "DEFAULT_MIXER_DEVICE" parameter.
|
||||
|
||||
Eg: if desired mixer is "2", modify "config.h.in" as below:
|
||||
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.
