Bug 1284119

Description of problem:

I have a ThinkPad 450s running fully updated Fedora 22 and KDE (qt5, etc.). The mini-DP port is connected to external monitor (TV) via DP-HDMI connector. The audio jack is connected to an external sound system with speakers.

I am not able to make the sound go to the sound system. I have two devices,

$ lspci | grep -i audio
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)

They both show (in kmix and systemsettings5 alike) as Built-In Audio Analog Stereo and Built-in Audio Digital Stereo (HDMI). I have Analog preferred over Digital for everything, but I can't save my preferences in the Audio Hardware Setup tab. Both devices show up as Built-In Audio, but it's obvious which is which. When I pick Analog (+ Profile) and click Apply and OK, nothing changes - no sound. When I re-open the tab (or the KMix Settings) I see HDMI selected again as if I did not change anything. Restarting X or rebooting does not help.

I also tried "xrandr --output HDMI1 --set audio off" and similar, in vain.

How can I select an audio card and save the settings?

Version-Release number of selected component (if applicable):

kmix-15.04.0-1.fc22.x86_64

How reproducible:

Always.

Steps to Reproduce:

1. Open KMix Settings or System Settings -> Multimedia. 

2. Go to Audio Hardware Setup tab. Assume there are two HW devices: Analog and Digital (HDMI).

3. Choose the Analog Device (should be obvious from the associated profile), click Apply and OK, close the tab and/or the window.

4. Reopen the Window/Tab.

Actual results:

HDMI is chosen as if no changes were made. No sound goes to the sound system connected to the audio port. As long as the audio port is connected there is no sound at all.

Expected results:

Chosen settings should be applied. I should have sound through the system connected to the audio port.

Additional info:

1. Everything worked fine before the series of KDE/kf5/qt5/plasma updates starting roughly a week ago (Nov 12-13 onwards). There were much more serious problems with the graphical environment that seem to have been largely fixed. I am confident though that there is no problem with the sound system, and it does seem to be a software issue that has not been fixed yet.

2. ~/.config/kmixrc shows

DefaultCardOnStart=PulseAudio.Playback_Devices.1.default

and then at least 3 entrie with the above prefix, which may be correct but my intuition makes me suspicious:

[View.PulseAudio.Playback_Devices.1.default.PulseAudio::Playback_Devices:1.alsa_output.pci-0000_00_03.0.hdmi-stereo]
[View.PulseAudio.Playback_Devices.1.default.PulseAudio::Playback_Devices:1.alsa_output.pci-0000_00_03.0.hdmi-stereo-extra2]
