Yes, thanks...  Something is wrong with the device: the test with Audacity is
negative.  Besides, today I got a new USB audio card, that I bought in internet
when I saw that the first one wouldn't work: here it is:

 https://www.amazon.it/dp/B01KLZR3TY/ref=pe_3310731_189395851_TE_dp_1

I bought it because it was claimed to be working with Linux.  And in fact, it
works perfectly, also with the test you suggested with pavucontrol, and also
with this test in Audacity, and it records fine.  But maybe, it is simply that
the first one is defective...

Thank you indeed, Curt, for your help...  Thanks to all.

Cheers,

Rodolfo

Right.

I have successfully recorded my speaking voice using a usb sound device
(webcam, but that's all I got) with audacity.

So you attach your usb dongle and plug in your microphone (turn it on, if it
turns on), then open audacity.

There are two microphone icons with drop down menus on the toolbar in
audacity. Next to the lower left microphone icon, I selected 'USB
Device' (hw:2,0) in the drop down menu.  The mic's mono so no choice
there for me. 

For the upper right mic icon select 'start monitoring' in the drop down
menu. Now when you make a sound into the microphone the red monitoring
meter should hop to the right. If that doesn't happen you can stop right
there because something is wrong that must be fixed first. No meter
movement--no sound input detected; you will end up with another empty
wav. 

Press red button to record.

Yes everything.  Voice is recorded fine if the microphone is plugged into the
`mic' entry of the PC, with the command `sox -t alsa default output.wav'.  So
it is not busted.  It's not a matter of loudness either...

What's this for?  ffmpeg complains:

How?  I see a list of three input devices:

 Monitor of Built-in Audio Analog Stereo
 Built-in Audio Analog Stereo
 CM108 Audio Controller Analog Mono

How do I choose the one I want?  Each of them has a red button with a check in
it, but nothing changes if I click on them...

Well, no, wherever I click that level does not arise...

It's strange to record to the same device number you listened to above, but
who knows?

There's only one input device on the dongle. Have you tried recording to
the laptop's mic with the sox command below? Does that work? Is your
microphone busted? Are you singing loud enough (from the diaphragm)?

>  $ sox -t alsa hw:2,0 output.wav

ffmpeg -f alsa -i hw:2 -t 30 out.wav

Thirty seconds. 

I'd open pavucontrol, select your usb audio dongle's mic as your input
device, start singing (after plugging in your microphone), and see if
you can get that input level gauge to start hopping to the tune of your
dulcet tenor arpeggios on the upper end of the Richter scale.

I had the USB work with headphones doing:

 $ mplayer -ao alsa:device=hw=2.0 

Can this help to solve also the recording problem...?  I get no sound recorded
doing:

 $ sox -t alsa hw:2,0 output.wav

If you were running pulseaudio, you would merely select the headphones. 
I suggest you use USB headphones. They are cheap. Works a charm. Ric

It seems it does: now I get:

but still the card does not work, neither with headphones nor with microphone:
to record from mic, I do now:

 $ sox -t alsa hw:1,0 output.wav

but no sound is recorded.

/etc/modprobe.d/sound 


  options snd-usb-audio index=0
  options snd_hda_codec_hdmi(or whatever it's called)=1
  options snd(etc...)=2

There's a plethora of info on sound card ordering, but much of it is
obsolete I'm afraid.

Whether making the usb dongle the default card by creating a ~.asoundrc file:

pcm.!default {
type hw
card 2
}

ctl.!default {
type hw
card 2
} 

would work or not I dunno. I read that for the Lenovo to get an external
usb sound card working the card must be indexed as card 0 (numero uno).

No  '/etc/modprobe.d/alsa-base.conf' on my PC...  /etc/modprobe.d is empty.
There's /usr/share/alsa.conf, but it doesn't contain any occurrence of `usb'.

Try making the USB audio dongle the first sound card (0).

I'm not certain how to do that.

Perhaps comment out the following line in '/etc/modprobe.d/alsa-base.conf':

 # Keep snd-usb-audio from beeing  loaded as first soundcard
 options snd-usb-audio index=-2

That's good and encouraging news. Wasn't the question I asked,
but you can't have everything.

My little mixer widget has a slider to adjust the input volume on the selected
device, as well as a gauge indicating the input level.

Testing, one, two, three.

Before you abort, did you see any indication - these percent signs are

If not, is it perhaps muted?

You can use to unmute

alsamixer -c 2

-c 2 is for the second card not to mix up with arecord -c1 which is telling
arecord to use mono input

A short howto I wrote years ago

1) find out cards and inputs

shell> cat /proc/asound/cards
 0 [Intel  ]: HDA-Intel - HDA Intel
  HDA Intel at 0xff95 irq 22
 1 [HVR900 ]: USB-Audio - WinTV HVR-900
  WinTV HVR-900 at usb-:00:1a.7-3, high speed
 2 [Webcam ]: USB-Audio - Philips SPC 1000NC Webcam
  Philips CE Philips SPC 1000NC Webcam at
usb-:00:1a.7-5.4, high speed

=> I'm going to use the Webcam built in mic => card # 2

2) find out the input

shell> cat /proc/asound/devices
  0: [ 0]   : control
  1:: sequencer
  6: [ 0- 2]: hardware dependent
  7: [ 0- 3]: hardware dependent
 16: [ 0- 0]: digital audio playback
 17: [ 0- 1]: digital audio playback
 19: [ 0- 3]: digital audio playback
 24: [ 0- 0]: digital audio capture
 32: [ 1]   : control
 33:: timer
 56: [ 1- 0]: digital audio capture
 64: [ 2]   : control
 88: [ 2- 0]: digital audio capture

=> my input is the capture on the second card

 88: [ 2- 0]: digital audio capture

3) so no we can test the mic

shell> arecord -c1 -Dplughw:2,0 -f cd -vv /dev/null

Assuming dmesg is producing any output (some systems may require
root), try the address above instead (keeping the -i).

dmesg | grep -i 013c -A 10 -B 10

Unfortunately I threw away the box, but it's just this:

 http://www.dx.com/p/usb-3d-sound-adapter-color-assorted-5831#.WYiR0q2dK00

I had it tested with MS Windows and works fine.  Under Linux, as I wrote, it is
detected by arecord and lsusb, and also by Audacity, and also by alsamixer, but
does not produce nor record any sound.

What do you suggest...?

Thanks,

Rodolfo

Help with USB audio card

Hi all.

I just bought an external USB audio card.  I plugged it into the USB port of my
