I have the same problem here, and adding -format s24le wont help. I
think it's because there's a difference between s24le and s24_3le (?)
and I don't know a -format option for s24_3le. Mplayer tries to play
s24le, while my /etc/asound.conf says my device uses s24_3le. If I try
to set asound.conf to s24le alsa says my device doesn't support it.
