If a sound file on ramdisk works while a sound file from USB hangs, then it is very likely a driver/DMA issue. Of course, it is impossible to know for sure without debugging the issue. I tested wavplay and madplay with audio files on hard disk and NFS. Both worked for me in the 2.6.10 kernel. Also, you may want to make sure you have applied all the released patches.
