Known error with signed samples at high samplerate?

Known error with signed samples at high samplerate?

[Garrett Kajmowicz]

Is there a known error requesting signed integer samples at a high (44100+) 
sample rate?

I am using the plughw interface on a SBLive! value card.  When I request 
samples as listed above, snd_pcm_readi always returns -EPIPE.  This does not 
occur at lower sample rates or with unsigned samples.

Thanks for the info.

-EPIPE means buffer overrun error (in capture direction).
you likely called readi() too lately.
