Oh, ok. I've asked only because some time ago I wrote a small tool set to get random bits from /dev/audio and feed them to /dev/random (ala audio-entropyd, but it does FIPS 140-2). You can configure how many bits to account via RNDADDTOENTCNT every N bits you write to /dev/random (I use 1/80). Since in principle it can take random data from any source, I'd wondered if someone had an esteem of the parameter for HRNGs. Thanks anyway.
