Try http://www.mplayerhq.hu/~rtognimp/ualaw/

The single channel files (surge-1...) work, the stereo don't (they may  
work with your patch, didn't tested yet)

I had similar problems with twos, fixing one kind of files broke the  
others. My conclusion (for twos) was that it's not fixable in the  
decoder, but the good values have to be filled in in the demuxer (don't  
ask me how).

But maybe for u/alaw the solution ss_mul = channels always works (worth  
a try, these fiels are not very common).
