The problem sounds familiar: I had the same problems when downsampling from the 48000 Hz input of my sound card to a 44100 Hz file. I'm told that if you needed to downsample output the same thing would happen; I needed to upsample output from 44100 to 48000 and would get some minor distortion but nothing serious. I got around that small distortion by sending my output through arts (kde's sound daemon) configured to output at 48000 Hz; apparently arts's upsampling worked better than the native driver's. You could try something like that too, or get hold of a sound file whose rate is the same as your card's and play that directly.
