[alsa-devel] ioctl problem - help please!!
Good day to everyone.
I'm developing a system in which I need to gather some entropy from /dev/random. In order to increase the entropy, I'm using a daemon called audio-entropyd from Folkert van Heusden, but it has some problems that maybe you guys can help me with this.
Does anybody know what might cause this:
2925 open("/dev/snd/pcmC0D0c", O_RDWR|O_NONBLOCK) = 5 2925 ioctl(5, 0x80184151, 0x7ffff3351890) = -1 EIO (Input/output error)
to give EIO?
The daemon just stops with the KILL signal.
Thanks for reading this, I really need your assistance for this please.
Regards,
René.

Some error detected by the driver. Which driver? Does normal recording work?

Thanks a lot for your reply Clemens.
The driver is Type

The driver is Type 10 ALSA emulation.
Yes, normal recording just works fine with the following command:
arecord -f dat -d 2800 audioDAT.wav
I'll wait for your comments, and thanks again.
René.
