Thus I should see internal speakers and HDMI outputs in Gnome control center but I can only see internal speakers. It's clearly a kernel issue since switching back to 3.19.0-16 solves this bug. I did no kernel tweaks. TLP is installed though. uname -a Linux 3.19.0-17-generic #17-Ubuntu SMP Wed May 6 16:46:12 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux lspci 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b) 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b) 00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04) 00:16.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04) 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I218-LM (rev 04) 00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 6 (rev e4) 00:1c.1 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 3 (rev e4) 00:1d.0 USB controller: Intel Corporation 8 Series USB EHCI #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation 8 Series LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 8 Series SATA Controller 1 [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 8 Series SMBus Controller (rev 04) 03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 83) --- ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ft 1770 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 15.04 HibernationDevice: RESUME=UUID=54b265b9-4433-42d4-8d0f-fac028ee7030 InstallationDate: Installed on 2014-03-05 (430 days ago) InstallationMedia: Ubuntu-GNOME 14.04 "Trusty Tahr" - Alpha amd64 (20140226) Lsusb: Bus 003 Device 002: ID 8087:8000 Intel Corp.
