I am using my CPUs IGP (Intel HD2000) and the onboard HDMI-plug of my motherboard (AsRock Z68 Pro3) to connect my TV and my pc.
There is no error when I try to play music in mplayer, just no sound.

Output of alsa-info

I even tried booting from an Ubuntu LiveUSB to see if another distro works and why, but no sound there as well.

Any ideas?

edit: marked as solved.

Code:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]

  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

You need to set one of these HDMI outputs as default in your .asoundrc (or /etc/asound.conf for systemwide setting).

Thanks for the hint.

First I was even more confused than I was before, but at least I got something out my TV-Speakers :D

what I did to my /etc/asound.conf:

Code:
# **** List of PLAYBACK Hardware Devices ****
# card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
#   Subdevices: 1/1
#   Subdevice #0: subdevice #0
# card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
#   Subdevices: 1/1
#   Subdevice #0: subdevice #0
# card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
#   Subdevices: 1/1
#   Subdevice #0: subdevice #0
# card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
#   Subdevices: 1/1
#   Subdevice #0: subdevice #0

pcm.!default {
        type  plug
        slave.pcm "hdmi1"
}

pcm.analog {
        type hw
        card 0
        device 0
}

pcm.digital {
        type hw
        card 0
        device 1
}

pcm.hdmi0 {
        type hw
        card 0
        device 3
}

pcm.hdmi1 {
        type hw
        card 0
        device 7
}


Using aplay I was able to generate some static noise through my TV-Speakers
Code:
aplay -Dplug:hdmi1 /media/Music/01\ Generator.mp3

Although the song is called generator, some bad religion coming out of the speakers would be better than just static.

edit: just looking at the debug output: "playing raw data" "Unsigned 8 bit" "Rate 8000 Hz" "Mono"
smells like I should play *.wav :oops:

edit2: after playing a wav file it works.
how do I reconfigure my /etc/asound.conf to do this?

edit3: updated the /etc/asound.conf to use hdmi1 as default wooorks! :D
