I've tried S24_3LE, S24LE, S24_BE, S24_3BE, FLOAT_LE, and FLOAT_BE.
None of them produce sound except for S24_3LE. S16_LE works, but
stills suffers from the static problem. Is there another format I
should try?

I did that by removing /etc/asound.conf and doing 'aplay file.wav',
but it produces the same static problem. I really think dmix is not
using the specified samplerate or speexrate.
