Skype - no video and no microphone

I am having big problem with my skype - installed from multilib repo, first the camera isn't detect:

ERROR: ld.so: object '/usr/lib32/libv4l/v4l2convert.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
ERROR: ld.so: object '/usr/lib32/libv4l/v4l2convert.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

I have no idea why this error appears - because I am running x86_64 system, so preloading the  /usr/lib32/libv4l/v4l2convert.so for skype should work.
Second my microphone doesn't work, maybe because my sound setup, here is my /etc/asound.conf:

# the sound card
pcm.real {
  type hw
  card 0
  device 0
}

# the ipc stuff is needed for permissions, etc.
pcm.dmixer {
  type dmix
  ipc_key 1024
  ipc_perm 0666
  slave.pcm "real"
  slave {
    period_time 0
    period_size 1024
    buffer_size 8192
    rate 44100  
  }
  bindings {
    0 0
    1 1 
  }
}

ctl.dmixer {
  type hw
  card 0
  }

# software volume
pcm.softvol {
  type softvol
  slave.pcm "dmixer"
  control {
    name "Software"
    card 0
  }
}
# mpd volume control
pcm.mpdvol {
  type softvol
  slave.pcm "dmixer"
  control {
    name "MPD"
    card 0
  }
}
# ctrl for mpd volume
ctl.mpdvol {
  type hw
  card 0
}

# input
pcm.input {
        type dsnoop
        ipc_key 3129398
        ipc_key_add_uid false
        ipc_perm 0660
        slave.pcm "810"
}

# duplex device
pcm.duplex {
        type asym
        playback.pcm "softvol"
        capture.pcm "input"
}

# default devices
pcm.!default {
  type plug
  slave.pcm "duplex"
}

# for oss devices
pcm.dsp0 {
  type plug
  slave.pcm "duplex"
}

And ~/.asoundrc:

# the sound card
pcm.real {
  type hw
  card 0
  device 0
}

# the ipc stuff is needed for permissions, etc.
pcm.dmixer {
  type dmix
  ipc_key 1024
  ipc_perm 0666
  slave.pcm "real"
  slave {
    period_time 0
    period_size 1024
    buffer_size 8192
    rate 44100  
  }
  bindings {
    0 0
    1 1 
  }
}

ctl.dmixer {
  type hw
  card 0
  }

# software volume
pcm.softvol {
  type softvol
  slave.pcm "dmixer"
  control {
    name "Software"
    card 0
  }
}
# mpd volume control
pcm.mpdvol {
  type softvol
  slave.pcm "dmixer"
  control {
    name "MPD"
    card 0
  }
}
# ctrl for mpd volume
ctl.mpdvol {
  type hw
  card 0
}

# input
pcm.input {
        type dsnoop
        ipc_key 3129398
        ipc_key_add_uid false
        ipc_perm 0660
        slave.pcm "810"
}

# duplex device
pcm.duplex {
        type asym
        playback.pcm "softvol"
        capture.pcm "input"
}

# default devices
pcm.!default {
  type plug
  slave.pcm "duplex"
}

# for oss devices
pcm.dsp0 {
  type plug
  slave.pcm "duplex"
}

pcm.skype {
   type asym
   playback.pcm "skypeout"
   capture.pcm "skypein"
}

pcm.skypein {
   # Convert from 8-bit unsigned mono (default format set by aoss when
   # /dev/dsp is opened) to 16-bit signed stereo (expected by dsnoop)
   #
   # We cannot just use a "plug" plugin because although the open will
   # succeed, the buffer sizes will be wrong and we will hear no sound at
   # all.
   type route
   slave {
      pcm "skypedsnoop"
      format S16_LE
   }
   ttable {
      0 {0 0.5}
      1 {0 0.5}
   }
}

pcm.skypeout {
   # Just pass this on to the system dmix
   type plug
   slave {
      pcm "dmix"
   }
}

pcm.skypedsnoop {
   type dsnoop
   ipc_key 1133
   slave {
      # "Magic" buffer values to get skype audio to work
      # If these are not set, opening /dev/dsp succeeds but no sound
      # will be heard. According to the ALSA developers this is due
      # to skype abusing the OSS API.
      pcm "hw:0,0"
      period_size 256
      periods 16
      buffer_size 16384
   }
   bindings {
      0 0
   }
}

I have tried this setup https://wiki.archlinux.org/index.php/skype#ALSA ALSA + Dmix.

Re: Skype - no video and no microphone

Hello. I had the same problem. Solved it by reinstalling the packages v4l-utils and lib32-v4l-utils.

Re: Skype - no video and no microphone

I have the same problem with Skype. Reinstalling packages does not help.
Any other idea?
