Yes sorry, when I write "sound HS" I mean that I hear no sound on the TV via the HDMI output.

The sound output is configured via sound settings (pavucontrol) to HDMI ouput. The sound is OK with some apps, and KO with some others. For example in VLC, it works usually fine. But on chromium/youtube, the sound is HS. Actually, i think it's not really a per app problem, but it might depend more on the type of audio being played. I thought the audio was working fine on firefox youtube at first, but once I ran into a specific video with the audio HS (and I checked this video had sound). When the audio is HS on a video play, if I start a video that usually doesn't have the problem, this video has the audio HS too. And reversely, if the audio is OK on a video, and if I start a video that usually have the problem, this time the video has its audio OK. Knowing this, I made a small sript to "fix" the audio of a video witht he problem. I pause the video with the audio problem, I start a sound hat usually doesn't have the problem, and I change the audio output back and forth to HDMI output again. It usually fixes audio, and I jsute need to resume the video with the problem BEFORE the good audio is over, and it's OK. This is my script mpv /path/to/whitenoise_48k.wav & pacmd set-card-profile 0 output:analog-stereo pacmd set-card-profile 0 output:hdmi-stereo And it's interesting to note that the same sound in 44k doesn't work (whitenoise_44k.wav). Weird stuff... These are the outputs of some commands, can make more if you want. aplay --list-devices **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC662 rev3 Analog [ALC662 rev3 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 1: ALC662 rev3 Digital [ALC662 rev3 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 lspci -v 00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04) Subsystem: Acer Incorporated [ALI] 7 Series/C216 Chipset Family High Definition Audio Controller Flags: bus master, fast devsel, latency 0, IRQ 30 Memory at f7e30000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel pacmd list-cards 1 card(s) available. index: 0 name: <alsa_card.pci-0000_00_1b.0> driver: <module-alsa-card.c> owner module: 22 properties: alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0xf7e30000 irq 30" 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 = "1e20" device.product.name = "7 Series/C216 Chipset Family High Definition Audio Controller" device.form_factor = "internal" device.string = "0" device.description = "Built-in Audio" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" profiles: input:analog-stereo: Analog Stereo Input (priority 60, available: no) output:analog-stereo: Analog Stereo Output (priority 6000, available: no) output:analog-stereo+input:analog-stereo: Analog Stereo Duplex (priority 6060, available: no) output:iec958-stereo: Digital Stereo (IEC958) Output (priority 5500, available: unknown) output:iec958-stereo+input:analog-stereo: Digital Stereo (IEC958) Output + Analog Stereo Input (priority 5560, available: unknown) output:hdmi-stereo: Digital Stereo (HDMI) Output (priority 5400, available: unknown) output:hdmi-stereo+input:analog-stereo: Digital Stereo (HDMI) Output + Analog Stereo Input (priority 5460, available: unknown) off: Off (priority 0, available: unknown) active profile: <output:hdmi-stereo> sinks: alsa_output.pci-0000_00_1b.0.hdmi-stereo/#5: Built-in Audio Digital Stereo (HDMI) sources: alsa_output.pci-0000_00_1b.0.hdmi-stereo.monitor/#5: Monitor of Built-in Audio Digital Stereo (HDMI) ports: analog-input-mic: Microphone (priority 8700, latency offset 0 usec, available: no) properties: device.icon_name = "audio-input-microphone" analog-output-headphones: Headphones (priority 9000, latency offset 0 usec, available: no) properties: device.icon_name = "audio-headphones" iec958-stereo-output: Digital Output (S/PDIF) (priority 0, latency offset 0 usec, available: unknown) properties: hdmi-output-0: HDMI / DisplayPort (priority 5900, latency offset 0 usec, available: yes) properties: device.icon_name = "video-display" device.product.name = "SAMSUNG" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1756198/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
