Hi everyone . I am writting an app and just realized that in first generation of iPod touch there is no control for Volume in the left side. So I have to implement the volume adjuster. Can you give me some ideas about what should I do? Since, I am very very new to coreAudio and I am hopping this can be accomplished without coreAudio. But if no, then coreAudio is what I have to study! Thanks in advance.
