As if by magic, KDE and KMix suddenly became aware of the HDMI profile, and sound subsequently switched. Since "pavucontrol" was already installed (by me IIRC), I used it to configure/select HDMI output (strange it claimed it was unplugged!). There was no mention of HDMI in KMix/audio setup or KDE's multimedia settings. Once I had managed to alternate screens with the desired resolutions (yet more fiddling about) and with video finally playing on TV, like you said the sound didn't switch. I just tried the HDMI connection on 13.1/KDE for the first time, as I have always used Win 7 supplied with this ThinkPad (a mere 5 year-old now), for output on a modern TV (BTW Win 7 also had a wizard to detect and correctly configure a TV). As far as I remember, same thing was with openSUSE 13.1.You remembered well. PS Right now I'm using Tumbleweed, but problem wasn't Tumblweed specific. Likely that answer won't satisfy you, but maybe it will help explain a bit that others have different view than what you have on this I know I for one would NOT want my audio automatically routed by default to HDMI if it were plugged in, but rather by default I would want it to may speakers with me having complete control to redirect to HDMI only if I wished to do so. Wrt the why to manually change the output device, that likely is associated with a general philosophy of GNU/Linux where control is passed the users and not done automatic. I'll try to test this ASAP, though I still don't understand why should I install some additional software for that basic functionality AND why should I manually change the output device.as to the 'why' to install additional software (in KDE) likely that basic design philosophy of the developers/packagers of the KDE desktop, which we are not (we are volunteers on this forum). I have installed pavucontrol and I think I have some additional options in kmixer. I guess problem can be resolved if I restart alsa, but there was no rcalsasound or alsasound in my system.
