Hi, I'm using Debian Jessie, KDE 4.14.2. At some point over the last 6 months or so a couple of related problems appeared on my desktop...

1) Sometimes sound appears not to be working and I have to go to change the output device to get this to work (right click on kmix, audio setup, hardware setup, device conguration dropdown to change between analog output and speaker.. -see screenshot http://pasteboard.co/RUjRaCJ.png). This is often a problem but is particularly a problem if I boot up with a headphone/speaker plugged into the jack...then if I remove this, it doesn't output to the laptop built-in speakers unless I change the settings.
What I want it to do is fairly straightforward, I just want it to use the laptop speakers when nothing is plugged in, but use headphone/external speaker output if i put something in the headphone jack.

2) I have lots of sliders when I click on kmix in my taskbar - I don't really understand what all of these do, they seem like duplicates...and also, sometimes sliders for specific applications seem to behave independently, defaulting to very quiet, or so on - generally behaving strangely! see: http://pasteboard.co/RUySWID.png for a screenshot.
Similarly, when I click the button to go to mixer, I get multiple duplicate tabs, some with lots of sliders again - some with none: http://pasteboard.co/RUEl5Ql.png, http://pasteboard.co/RUFPTrw.png, and http://pasteboard.co/RUJBxsV.png.
I don't really understand why there are so many of these?

I also have a problem, much more minor, but perhaps related: when I'm playing music in banshee, if I reduce volume using the system volume (keyboard shortcuts/ kmix), it goes down in banshee...but doesn't go back up again. so if i mute system sound then unmute it, banshee stays muted and i have to use the specific setting within banshee...

I'm not sure where these problems came from as it all previously worked fine within kde for me. Perhaps i messed something up intentionally or perhaps an update caused this - if anyone could help me understand what's going on I'd be very grateful!

Cheers,
Nick

As several people have mentioned there is a, rather easy, work around which is opening your "playback devices" and changing your default audio each time you have that specific window open. I'm sure 4 whole clicks is a giant hassle for some of you but as of now that's the only solution you're going to get without some sort of 3rd party software or some jimmy rigging your browser (which I never recommend for others to do.)
Now I know I'm going to get a bunch of "I don't think this reply is helpful" and that's fine because people view it more as "like" and "dislike" but what I've told you is the truth. But the sense of self-entitlement you people have is absurd. If you have multiple sound cards and the know-how this is easy to do as well but with on-board sound you're a bit restricted.
