[pulseaudio-discuss] what is still missing?

[Matti Riikari]

I've ended up in dead end. Recording from default input produces just 
white noise. Everything is seemengly correct, but what is still missing?

I have a Deltaco UAC-03 USB sound card.

/etc/pulse/defaul.conf:
set-default-source 
alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback

pacmd list-sources | grep -e 'index:' -e device.string -e 'name:'

* index: 5
     name: <alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback>
         device.string = "hw:2"

parecord --record test.wav

When recording, pacmd list-sources shows the correct  source is activated:
Source #5
     State: RUNNING
     Name: alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback
     Description: USB Audio Device Mono

But the sound file is an empty recording. Checked with alsamixer mic is 
not muted.


Empty recording also by
parecord --record 
--device="alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback" 
test.wav

and
parecord --record 
--device="alsa_input.usb-GeneralPlus_USB_Audio_Device-00.mono-fallback" 
--volume=40000 --channels=1 test.wav

Same for
arecord test.wav

and
arecord --device="hw:2" test.wav

vumeter switch shows the truth, nothing is coming in. What am I missing?
arecord --vumeter=mono test.wav
Recording WAVE 'out.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono
#+                                                 | 00%




Thanks for any help to solve this.
