Using both a USB Mic and on board audio output - Raspberry Pi Forums

-

i'm trying set rpi on-board sound out , usb mic in, i've found deals both audio i/o on same (external) sound card. what's happening in situation regardless of default sound card set, either 1 of aplay or arecord fail error message looks like:

code: select all

arecord: main:682: audio open error: no such file or directory
(replace arecord aplay if default card set usb mic).

example, have following scenario:

in /etc/modprobe.d/alsa-base.conf, commenting out options snd-usb-audio index=-2 allow arecord work, not aplay, , uncommenting above line allow aplay work, not arecord

know can add device name when running command (example: arecord -dhw:1,0 test.wav works, arecord test.wav doesn't), not happen because i'm using bunch of pre-compiled libraries seem consider default devices

you can create 'asymmetric' alsa device uses both cards. in ~/.asoundrc, example:

code: select all

pcm.!default {     type asym     playback.pcm "hw:0,0"     capture.pcm "hw:1,1" }

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); ...

LED Strip Code

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) { ...
