Thanks for the hint with pavucontrol. Unfortunateley, pavucontrol shows in the profile selection menue the HDMI Output always as "unplugged":
"Digital Stereo (HDMI) Output (unplugged)" And also the corresponding output device: "HDMI / DisplayPort (unplugged)" Also the sink list shows the device as "available: no". I gues that is the problem. How could I get the HDMI Output recognized as "plugged in", what it really is? (With Ubuntu 14.10 it works) pacmd list-sinks 1 sink(s) available. * index: 52 name: <alsa_output.pci-0000_00_1b.0.hdmi-stereo> driver: <module-alsa-card.c> flags: HARDWARE DECIBEL_VOLUME LATENCY FLAT_VOLUME DYNAMIC_LATENCY state: IDLE suspend cause: priority: 9950 volume: front-left: 65536 / 100% / 0,00 dB, front-right: 65536 / 100% / 0,00 dB balance 0,00 base volume: 65536 / 100% / 0,00 dB volume steps: 65537 muted: no current latency: 18,52 ms max request: 3 KiB max rewind: 64 KiB monitor source: 61 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 0 linked by: 1 configured latency: 20,00 ms; range is 0,50 .. 371,52 ms card: 0 <alsa_card.pci-0000_00_1b.0> module: 6 properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "HDMI 0" alsa.id = "HDMI 0" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "3" alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0xfe620000 irq 48" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1b.0" sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "1c20" device.product.name = "6 Series/C200 Series Chipset Family High Definition Audio Controller" device.form_factor = "internal" device.string = "hdmi:0" device.buffering.buffer_size = "65536" device.buffering.fragment_size = "32768" device.access_mode = "mmap+timer" device.profile.name = "hdmi-stereo" device.profile.description = "Digital Stereo (HDMI)" device.description = "Internes Audio Digital Stereo (HDMI)" alsa.mixer_name = "Intel CougarPoint HDMI" alsa.components = "HDA:10ec0892,80862002,00100302 HDA:80862805,80862805,00100000" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" ports: hdmi-output-0: HDMI / DisplayPort (priority 5900, latency offset 0 usec, available: no) properties: device.icon_name = "video-display" active port: <hdmi-output-0> -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
