When I tried to add the volume control I could not compile the file anymore. I am hoping someone can help me and see what I am missing. I have looked in the Writing an Alsa Driver chapter 6 and I have looked at dummy.c . I believe I am following what they say to do but when I compile the file I get many errors including "warning: "struct snd_ctl_elem_info declared inside parameter list" I have at the top of my file #include <sound/control.h> along with the other includes I see in the sample files. Below is the code I added. > ALSA used to typedef all of these structs. Some people thought that obfuscated the code so the typedefs were removed between 1.0.8 and the current version. Looks like you're trying to add new-style code to old ALSA. Should compile against 1.0.8 if you replace "struct snd_foo" with "snd_foo_t" for all foo...
