I just received my UDOO X86 (4 gb ram, 32 gb mmc). I managed to install several flavours of Linux (Ubuntu 16.4, Lubuntu 16.4, Debian Jessie), but regardless the distribution it looks like I can't get any audio played by my TV through HDMI. Is anything specific I should check which can help out with the debug of this issue? Thanks for your help, -- Davide
My guess is that the default output channel is the jack. I think you have to configure it to HDMI. In Ubuntu this is done via the System Settings -> Audio.
Thanks for your reply, Maurice. Your guess was right, but unfortunately I can't still solve the problem. Since my last installation was a Debian Jessie, I've installed "pavucontrol" to check if it was possible to change something, but all the HDMI available "profiles" shows their entries as "unplugged" and regardless the choice, I still have no audio output on my TV. Any other suggestion? From the command line, I've gathered this information: --- davide@vinales:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog] 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 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 davide@vinales:~$ pacmd list-sinks 1 sink(s) available. * index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo> driver: <module-alsa-card.c> flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY FLAT_VOLUME DYNAMIC_LATENCY state: SUSPENDED suspend cause: IDLE priority: 9959 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: yes current latency: 0.00 ms max request: 0 KiB max rewind: 0 KiB monitor source: 0 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 0 linked by: 0 configured latency: 0.00 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 = "ALC283 Analog" alsa.id = "ALC283 Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0x91410000 irq 134" 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 = "2284" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "65536" device.buffering.fragment_size = "32768" device.access_mode = "mmap+timer" device.profile.name = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Built-in Audio Analog Stereo" alsa.mixer_name = "Intel Braswell HDMI" alsa.components = "HDA:10ec0283,10ec0283,00100003 HDA:80862883,80860101,00100000" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" ports: analog-output: Analog Output (priority 9900, latency offset 0 usec, available: unknown) properties: analog-output-speaker: Speakers (priority 10000, latency offset 0 usec, available: unknown) properties: device.icon_name = "audio-speakers" analog-output-headphones: Headphones (priority 9000, latency offset 0 usec, available: no) properties: device.icon_name = "audio-headphones" active port: <analog-output-speaker> --- After changing the profile from the pavucontrol gui, the last command now displays different information, but still no audio: --- davide@vinales:~$ pacmd list-sinks 1 sink(s) available. * index: 12 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: RUNNING suspend cause: priority: 9950 volume: front-left: 91607 / 140% / 8.73 dB, front-right: 91607 / 140% / 8.73 dB balance 0.00 base volume: 65536 / 100% / 0.00 dB volume steps: 65537 muted: no current latency: 19.58 ms max request: 3 KiB max rewind: 64 KiB monitor source: 15 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 1 linked by: 3 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 0x91410000 irq 134" 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 = "2284" 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 = "Built-in Audio Digital Stereo (HDMI)" alsa.mixer_name = "Intel Braswell HDMI" alsa.components = "HDA:10ec0283,10ec0283,00100003 HDA:80862883,80860101,00100000" 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> --- -- Davide
