Pulseaudio missing profile 7.1
I have all time present profile (several years): Analog Surround 7.1 Output
But after last two months, missing this profile completely and there is maximal Analog Surround 5.1 Output. I tried to older kernels, but it is not by kernel, it seems that it is some updated version of pulseaudio.
I'm using
alsa.card = "1"
alsa.card_name = "HD-Audio Generic"
alsa.long_card_name = "HD-Audio Generic at 0xfcc00000 irq 138"
alsa.driver_name = "snd_hda_intel"
device.bus_path = "pci-0000:31:00.4"
sysfs.path = "/devices/pci0000:00/0000:00:08.1/0000:31:00.4/sound/card1"
device.bus = "pci"
device.vendor.id = "1022"
device.vendor.name = "Advanced Micro Devices, Inc. [AMD]"
device.product.id = "1487"
device.product.name = "Starship/Matisse HD Audio Controller"
device.string = "1"
device.description = "Starship/Matisse HD Audio Controller"
module-udev-detect.discovered = "1"
device.icon_name = "audio-card-pci"
