Hi,

i am just trying to start the rpi-test.sh on my raspberry pi 3

The 820T2 usb device is well detected.

For the audio device i installed an external usb sound card (as suggested)

I can see it in the list of device, but when i select it it doesn’t work.

ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM 0

arecord: main:722: audio open error: File o directory non esistente

The device is detected it has DEV=0.

But also bcm2835 ALSA, bcm2835 IEC958/HDMI has DEV=0

Here is what i get:



Do you have your RTL-SDR and an USB audio card connected? [y/n] y

Now I will list all the ALSA devices on your system.

You will have to choose one USB audio device ID.

Entries will look something like this:

hw:CARD=Device,DEV=0 <==== This is the device ID of the entry; you will need this.

Now we will try to record 15 seconds of audio from the microphone input.

Press any key to continue.
