Hello,
I can't get 4.0/5.1 sound working on my laptop [0] [1] with Fedora 22. With Linux 4.0 there is no output on jacks but with 4.1-rc6 I'm getting sound only on one output. Switching between pacmd set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo and pacmd set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-surround-40 only boosts the volume on the first output.
Attached is dmesg, lsmod, result of lspci -vv and pacmd list-cards and list-sinks and output of various information from /proc/asound while runnig 4.1-rc6.
Let me know if you need more information or how I can help.
Best regards, Nicolae Rosia
