no sound recorded with Simplescreenrecorder

Before, I could record videos from YouTube in Plasma without any problems. Last days, I've been trying doing from  XFCE and I can record the video but not the audio. In simplescreenrecorder, I can choose ALSA, PULSEAUDIO or JACK. I made some tests:
ALSA has different sources:

• [default] Default source --> no sound recorded
  [sysdefault:0] HDA Intel MID (shared) --> no sound recorded
  [hw:0,0] HDA Intel MID: VT1828S Analog --> no sound recorded
  [hw:0,2] HDA Intel MID: VT1828S Alt Analog --> no sound recorded
  [sysdefault:2] USB Device 0x46d:0x821 (shared) --> sound recorded from the USB webcam
  [hw:2,0] USB Device 0x46d:0x821: USB Audio --> sound recorded from the USB webcam

PULSEAUDIO shows no source at all.

If I select JACK and "record system speakers", when I initialize the recording, it gives me this error:
[JACKInput::Init] Error: Could not connect to JACK!
[PageRecord::StartPage] Error: algo ha salido mal durante la inicialización.

What I would like to do is to record the sound coming from the speakers of my screen as I was doing before in Plasma desktop. Any ideas why I can't?

Thanks in advance

Re: no sound recorded with Simplescreenrecorder

Do you have xfce's mixer installed? it likely hogs your audio device and you can't use anything else to access the audio device. Use

sudo fuser -v /dev/snd/*

to confirm. How did you have simplescreenrecorder set up on plasma? Via pulse or ALSA?

Re: no sound recorded with Simplescreenrecorder

Thanks for the reply.

This is the output you asked for:

sudo fuser -v /dev/snd/*
[sudo] password for david: 
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  david       640 F.... panel-16-mixer
/dev/snd/controlC1:  david       640 F.... panel-16-mixer
/dev/snd/controlC2:  david       640 F.... panel-16-mixer

Regarding to my previous settings in plasma, if I remember properly it was done via ALSA.

This confirms my suspicion, does it work if you kill the panel-mixer ?

I removed it from the panel, reboot my system and there is no audio anymore.

Update: The reason for it is that always I start my system, the volumen is off. I have to turn it up manually.

Open terminal and write

alsamixer

then hit F4 to go to Capture tab, if you can't see L R Capture on the bottom, hit space to unmute
