Settigng up mic volume / ALSA error - Raspberry Pi Forums

-

hi,
have usb sound card
bus 001 device 004: id 0d8c:000c c-media electronics, inc. audio adapter
/dev/snd/by-id/usb-0d8c_c-media_usb_headphone_set-00
on alsa hw:1
but
have compile , install alsa ftp://ftp.alsa-project.org/pub/lib/alsa ... .0.tar.bz2
in order compile ffmpeg alsa.

set mic volume , suppose done alsamixer, but:

code: select all

#alsamixer cannot open mixer: invalid argument #alsamixer -c1 cannot open mixer: invalid argument  #aplay -l **** list of playback hardware devices **** aplay: device_list:277: control open (0): invalid argument aplay: device_list:277: control open (1): invalid argument  #arecord -l **** list of capture hardware devices **** arecord: device_list:277: control open (0): invalid argument arecord: device_list:277: control open (1): invalid argument  #amixer -c1 -d amixer: mixer attach hw:1 error: invalid argument
mic working, sound great little quiet. before compiled aplay -l worked.
how can 1) repair raspberian alsa, 2) set mic volume up?
tried reinstall alsa-utils nothing changed.

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
