sorry, i know that the question might be silly but:
my audio board requires 48Ksps
the fm receiver in gnu radio examples delivers to it 32Ksps instead.
setting a overall decimation factor of 1320 i can get as near as 48484
samples/sec.
but even if much better, this still gives problems. and there’s no
integer factor that can take 64Msps to exactly 48Ksps.
can anyone help a newbie?
Thanks

I think you need a resampling function (or a smarter sound card
eg sox can resample from one frequency to another, I don’t know if there
is
such a block in GNURadio though.

If you’re using ALSA, try plughw:0,0
or
use gr-audio-oss instead.
