Certainly Sound Check via playback preferences is working with my libraries, all of which have iTunes Match enabled.
There are 3rd party utilities that have an ability to adjust playback levels, a good example is beatunes.

I'm with mracole. The sound check feature works fine in my local iTunes library. However I suspect you mean it is not working on your iPhone, correct? If you are listening to "matched" songs on your iDevice, then those songs come directly from the iTunes Store and would not have your sound check adjustments applied. So this actually makes sense. To my knowledge there the only way to apply sound check adjustments is directly on the iPhone. Go to Settings > Music and set Sound Check to ON if you have not already done so.

I have sound check enabled on my local iTunes library and all my iDevices, but the problem seems to occur when I playing songs directly from Match library. I use a third party app called iVolume to ensure that all my songs are playing at the same volume. However, I still get songs at different volumes.

I see. The local sound check option should work in iTunes and on iOS devices, but a 3rd party app like iVolume isn't going to work on "matched" songs you've downloaded directly from the iTunes store to your iDevice. How could it?

I have a similar problem to Nickcalifornia. I've been using mp3gain to normalize the volume of my tracks across the board for years, but match is throwing a wrench in the equation.
Michael Allbritton: Extended tags could work if iTunes Match saved each users meta data seperately, even for matched songs. However, that's opening up a can of worms I'm sure Apple won't touch.
However, even with Sound Check turned on everywhere, I'm still getting volume jumps between tracks. I'm not familliar enough with Sound Check to know if it's detection is really that bad or if Sound Check is failing entirely.

I have noticed this too. I have albums that I've uploaded that are from the 80s and recorded lower than new albums. They play fine with sound check in iTunes, but the same tracks aren't matched volumewise in my iPhone and iPad. I find this very annoying as I listen to music all night and I'll have one song quiet so I turn the volume up and then the next track is blasted in comparison to the previous. I'm too the point where I'm going to dump iTunes Match and go back to syncing with the comp if this problem isn't addressed soon. Btw I don't use a third party app at all and never have. This is something that they have changed since match was started.

I have noticed that Sound Check only works on songs you have locally. Anything that is streaming does not initially have it on. However, if you go to preferences and turn Sound Check off then on, then it applies to the currently streaming song. It doesn't stick when you go to the next song. I will probably file a bug report.
