Hi Clemens and friends,
I've some problem referents with alsa and get volume from mircophone:
1.- When to compile the file ,returned these lines.Could be problem to keep?
arm-gp2x-linux-gcc -o micro micro.c -lasound -static -lpthread -ldl -lm -lrt /usr/lib/gcc/arm-gp2x-linux/4.1.2/../../../../arm-gp2x-linux/lib/libasound.a(dlmisc.o): In function `snd_dlopen': /home/dam/alsa-lib-1.0.17/src/dlmisc.c:64: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
2.- The previous to say, despite being a warning can create executable file. But when return:
ALSA lib conf.c:3009:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL default Ret -2 Mic volume is -1
I'm sorpress because not exist this file, but the route /usr/share/ has others folders differents of alsa, Does it change the route?

Hi again,
Another question, how I can get the volume of the microphone real= dynamic? I like getting volume of the micro, to change volume of speakers.
I don't know if I will explain .

Hi Clemens,
I added 2 parameters and return:
# arm-gp2x-linux-gcc -o microphone microphone.c -lasound -static -ldl -lpthread
/usr/lib/gcc/arm-gp2x-linux/4.1.2/../../../../arm-gp2x-linux/lib/libasound.a(dlmisc.o): In function `snd_dlopen':

You still do not have -ldl and -lpthread.
