Not sure what the problem might be but when I try to run audio-entropyd on an Atom box I'm setting up as a router, it seems to fail pretty badly:


ichigo ~ # audio-entropyd -d hw:0 -v -n
audio-entropyd starting up
Get random data: read error: Input/output error



Debug information:
errno: 5=Input/output error (if applicable)
Obtained 7 stack frames:
audio-entropyd(+0x2d69)[0x1128dc1d69]

stracing it, the problem is here: (yes I had to fix strace for it to tell me which ioctl is the problem)

same problem with 2.0.3? do other apps like aplay -Dhw:0 work?
