Description amichai2 2015-01-27 10:25:21 UTC 
I've recently upgraded to Kubuntu 14.10 (KDE 4.14.2), and started getting this issue: Whenever my monitors enter energy savings mode (when pc is idle for a while - the pc itself is not suspended, only the monitors are), then the TV (connected as third display to PC) is no longer remembered as an audio output device.

So every time I want to use the TV I must go to K Menu -> System Settings -> Multimedia -> Audio and Video Settings -> Audio Hardware Setup -> Profile and re-select the proper profile. Sound Card is "Built-in Audio", and there are 3 different profiles in the dopdown list all identically named "Digital Stereo (HDMI) Output", however selecting each of them gives a different Connector name below: "HDMI / DisplayPort", "HDMI / DisplayPort 2 " and "HDMI / DisplayPort 3".

In my case the second one is the correct one, but when a screen energy savings mode is activated it reverts back to the third, which is incorrect.

This issue did not occur before the upgrade, and there were no other hardware changes.

See https://bugs.kde.org/show_bug.cgi?id=340979 for the previous history and discussion of this issue.

do you mean you have two hdmi connected ?

Active Profile: output:hdmi-stereo-extra1
	Ports:
		hdmi-output-0: HDMI / DisplayPort (priority: 5900, latency offset: 0 usec, not available)
			Properties:
				device.icon_name = "video-display"
			Part of profile(s): output:hdmi-stereo, output:hdmi-surround
		hdmi-output-1: HDMI / DisplayPort 2 (priority: 5800, latency offset: 0 usec, available)
			Properties:
				device.icon_name = "video-display"
				device.product.name = "PANASONIC-TV"
			Part of profile(s): output:hdmi-stereo-extra1
		hdmi-output-2: HDMI / DisplayPort 3 (priority: 5700, latency offset: 0 usec, available)
			Properties:
				device.icon_name = "video-display"
				device.product.name = "SyncMaster"
			Part of profile(s): output:hdmi-stereo-extra2
Comment 2 amichai2 2015-02-01 08:48:00 UTC 
I have a total of 3 connected: one monitor via DVI, one monitor via HDMI, and the TV via DP with a DP->HDMI active converter. In the KDE Display Settings they are identified as HDMI1, HDMI3 and DP1 respectively, but in the KDE Audio Hardware Setup under the first 'Built-in Audio' sound card there are 3 identically named 'Digital Stereo (HDMI) Output' options, which when selected, change the 'Connector' selection beneath it. The one showing connector 'HDMI/DisplayPort 2' is the TV. The other monitors don't have speakers on them, so selecting the other two profiles (with connectors 1 or 3) doesn't output any sound (and is not supposed to). Other than that there's a second 'Built-in Audio' sound card selection, but that's for all the analog output profiles (unrelated to monitors).

I hope that clarifies the setup :-)

xrandr --verbose


the workaround is to disable audio of your first hdmi by xrandr
