Hi people!
I'm starting withIntelEdison,I'm trying toconnect amicrophoneto the board, but I can't make it work.
I alreadyinstalledpackages:
- alsa (v 1.0.27)
- alsa-utils (v 1.0.27)
- kernel-module-snd-usb-audio (v 3.10.17)
- libusb (v 1.0)
- libav (v 0.8.9)
I connected my microphone in miniUSB input (J16) with usbOTG.
If I run:
