[CM] snd - right channel only silence when loading files

I have a problem with snd that if I open a stereo .wav file into snd,
only the left channel has audio, the right channel is only silence (with
the correct length).

I tried also to convert the .wav to .au using sox, but the result was
the same when loading the .au file.

Also, when hitting "sync" and then "play" from the lower right corner,
only the left channel plays.

Then I converted the audio file to mono (sox file.wav -c 1 monofile.wav)
and it loaded fine, and also played fine on both speakers.

Thus it seems it's a bug in the file loading part.

Some info about my system:

I'm a programmer, so I could maybe have a shot at debugging the program
if you could give me some pointers what to do and where.. or maybe try
switching some libraries it uses, if you suspect that to be the problem.

Thanks for your time,
