[CLAM] the object rightChannel is not ready (II)

[Xavi Rubio]

The problem is in the settings, because you must add SOURCES_AUDIODEVICE variable to the sources that the program needs to compile:

SOURCES = $(TOP)/MyCLAMApp.cxx \
        $(SOURCES_AUDIODEVICE)


As you have selected ALSA as your audio output library, this flag will contain all the needed code related to alsa.
