[No audio input] USB SoundCard

Jump to solution

Hi,

I have an issue to configure my edison to capture and stream audio. I use Ubilinux on Intel Edison. I install alsa

First I plug an USB SoundCard, a generic model with an USB OTG.

I found it quickly :

"lsusb" ->

Bus 001 Device 002: ID 0d8c:0014 C-Media Electronics, Inc. <-- This is my device</span>

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

I try my first "speaker-test"

No sound, so i check my /etc/asound.conf, This files does not exist.

So I do "aplay -l" ->

[...]

card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]

Subdevices: 1/1

Subdevice # 0: subdevice # 0

My "cat /proc/asound/cards"

0 [Loopback ]: Loopback - Loopback

Loopback 1

1 [Device ]: USB-Audio - USB Audio Device

C-Media Electronics Inc. USB Audio Device at usb-dwc3-host.2-1, full speed

On my /usr/share/alsa/alsa.conf, I change c

[...]

defaults.ctl.card 1 

defaults.pcm.card 1

[...]

Now, When i open alsamixer, it show me my mic and headphone volume. Great...

But I do again a speaker-test: again Playback device is default

I create my /etc/asound.conf with :

pcm.!default {

type plug

slave {

pcm "hw:1,0"

}

}

ctl.!default {

type hw

card 1

}

Finally, I try to record with

arecord -d 10 /tmp/test-mic.wav, // record raise my no issues

but

# aplay hw:1,0 -d 10 /tmp/test-mic.wav

Playing WAVE 'hw:1,0' : Unsigned 8 bit, Rate 8000 Hz, Mono

[ 578.725491] 2:1:1: usb_set_interface failed (-22)

I don't find the solution in other discussions .......

Thank you for your help !
