Hi.
Open a terminal window (ctrl+alt+t) and enter this command: pacmd list short sinks
.
Scroll with your mouse to figure out the name of your card and the right output in the profiles list.
Here's a bit of what it looks like in my case:
Example
2 card(s) available.
index: 0
name: <alsa_card.pci-0000_01_00.1>
driver: <module-alsa-card.c>
owner module: 7
properties:
alsa.card = "1"
alsa.card_name = "HDA ATI HDMI"
alsa.long_card_name = "HDA ATI HDMI at 0xfea60000 irq 68"
alsa.driver_name = "snd_hda_intel"
device.bus_path = "pci-0000:01:00.1"
sysfs.path = "/devices/pci0000:00/0000:00:02.0/0000:01:00.1/sound/card1"
device.bus = "pci"
device.vendor.id = "1002"
device.vendor.name = "Advanced Micro Devices, Inc. [AMD/ATI]"
device.product.id = "aac8"
device.product.name = "Hawaii HDMI Audio [Radeon R9 290/290X / 390/390X]"
device.string = "1"
device.description = "Hawaii HDMI Audio [Radeon R9 290/290X / 390/390X]"
module-udev-detect.discovered = "1"
device.icon_name = "audio-card-pci"
profiles:
output:hdmi-stereo: Sortie Digital Stereo (HDMI) (priority 5900, available: no)
output:hdmi-surround: Sortie Digital Surround 5.1 (HDMI) (priority 800, available: no)
output:hdmi-surround71: Sortie Digital Surround 7.1 (HDMI) (priority 800, available: no)
output:hdmi-stereo-extra1: Sortie Digital Stereo (HDMI 2) (priority 5700, available: no)
output:hdmi-surround-extra1: Sortie Digital Surround 5.1 (HDMI 2) (priority 600, available: no)
output:hdmi-surround71-extra1: Sortie Digital Surround 7.1 (HDMI 2) (priority 600, available: no)
output:hdmi-stereo-extra2: Sortie Digital Stereo (HDMI 3) (priority 5700, available: no)
output:hdmi-surround-extra2: Sortie Digital Surround 5.1 (HDMI 3) (priority 600, available: no)
output:hdmi-surround71-extra2: Sortie Digital Surround 7.1 (HDMI 3) (priority 600, available: no)
output:hdmi-stereo-extra3: Sortie Digital Stereo (HDMI 4) (priority 5700, available: no)
output:hdmi-surround-extra3: Sortie Digital Surround 5.1 (HDMI 4) (priority 600, available: no)
output:hdmi-surround71-extra3: Sortie Digital Surround 7.1 (HDMI 4) (priority 600, available: no)
output:hdmi-stereo-extra4: Sortie Digital Stereo (HDMI 5) (priority 5700, available: unknown)
output:hdmi-stereo-extra5: Sortie Digital Stereo (HDMI 6) (priority 5700, available: unknown)
You want to grab the name of the card you use, in this case alsa_card.pci-0000_01_00.1
and since I use Digital Stereo output (HDMI 6) in the preferences, I want the output:hdmi-stereo-extra5
output.
Once you get the right card name and output, you can set the default output using this command:
pactl set-card-profile card output
so in my case, pactl set-card-profile alsa_card.pci-0000_01_00.1 output:hdmi-stereo-extra5
.
When your command is ready, add it to the startup applications in the preferences. Add a new one, give it a name, paste your command in the command field and you should be good to go.
