sounds associated with player movement (splashes, footsteps, etc) are really quiet

the sounds that play when you walk around are extremely quiet. i have to crank the volume up on my computer to absolute max to hear them well, but this causes all the other sounds to be way too loud. all volume sliders in game are turned up to max, and i have the volume of minecraft set to 100 in windows volume mixer. the sounds seems to be louder in 1.7. i have not tried manually amplifying the audio files yet to see if it is an issue with the files themselves or with the way minecraft plays them, but playing the audio files in audacity makes a huge difference in volume.
