Kubuntu 12.04 Sound issues

It always seems like when a new version of Ubuntu is released, one can shortly find a host of Google results “Ubuntu [x.xx] NO SOUND PLEASE HELP!!!!”  Indeed this seems to be one of the small costs of open source software.  Still, it’s annoying.

Upon reinstalling my copy of 12.04 this morning, I learned that I was to fall victim to “NO SOUND”  Vaguely remembering that I fixed this somehow back in May (but being absolutely clueless of how I managed to do it), I set to work doing the standard hap-hazard solutions.  I checked the phonon settings, did some sort of uninstall/reinstall of pulse audio; you know, going through the motions that often stumble upon the fix without any decent understanding or appreciation of the underlying situation.

As usual the “System Settings” was of no use in this (rarely is).  But then I stumbled upon “Select Master Channel” by right clicking on my sound icon in the system tray.  (Remember, haphazard without any deep understanding.)

Anyway, when I clicked on it, I got the following window:

In my case, the high def audio controller was checked but I needed the Built in Analog Sterio.

Solved everything.

Now I don’t like to critisize free, but Kubuntu’s treatment of audio (particularly) has always confused me.  On the one hand they have this great “System Settings” pannel but when I go into the multimedia settings and tell it to prefer my analog system, nothing happens.  When I right click on the speaker in the system tray and bring up a window that claims to be for the same purpose, it’s apparently a completely different system.  What circumstances in development could have lead to this situation?  Blah, either way, can’t argue with free and open though.

Fixing blue tint in youtube videos

Ever since some time in late March, my Youtube videos have been blue.  I put up with it, figuring that once I upgraded to Kubuntu 12.04 (which I did this evening), everything would be fixed.  …nope.  So then I decided to use the Googler and figure out what to do.

Apparently it’s caused by a bug in the latest update for flash and Adobe is not being quick to correct it (we all know how long it took for them to acknowledge 64 bit computers).  But anyway, I did the following:

1)  I created a new adobe directory under etc

sudo mkdir /etc/adobe

2)  I then modified the Flash configuration by the following line of code that I blindly pasted into my terminal because the internetz told me to.  (I figured if it turned out we don’t want nOverrideGPUValidation, whetever the hell that is, to be true we could just delete the directory and hope everything goes back to normal)

echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null

Anyway, much to my delight, it worked.  Here’s the source of the info: http://askubuntu.com/questions/117127/flash-video-appears-blue
