I've ended up in dead end. Recording from default input produces
just white noise. Everything is seemengly correct, but what is still
missing?<br>
<br>
I have a Deltaco UAC-03 USB sound card.<br>
<br>
/etc/pulse/defaul.conf:<br>
set-default-source
alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback<br>
<br>
pacmd list-sources | grep -e 'index:' -e device.string -e 'name:'<br>
<br>
* index: 5<br>
name:
<alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback><br>
device.string = "hw:2"<br>
<br>
parecord --record test.wav<br>
<br>
When recording, pacmd list-sources shows the correct source is
activated:<br>
Source #5<br>
State: RUNNING<br>
Name:
alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback<br>
Description: USB Audio Device Mono<br>
<br>
But the sound file is an empty recording. Checked with alsamixer mic
is not muted.<br>
<br>
<br>
Empty recording also by<br>
parecord --record
--device="alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback"
test.wav<br>
<br>
and<br>
parecord --record
--device="alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback"
--volume=40000 --channels=1 test.wav<br>
<br>
Same for<br>
arecord test.wav<br>
<br>
and<br>
arecord --device="hw:2" test.wav<br>
<br>
vumeter switch shows the truth, nothing is coming in. What am I
missing?<br>
arecord --vumeter=mono test.wav<br>
Recording WAVE 'out.wav' : Signed 16 bit Little Endian, Rate 8000
Hz, Mono<br>
#+ | 00%<br>
<br>
<br>
<br>
<br>
Thanks for any help to solve this.<br>
