[alsa-devel] snd_pcm_poll_descriptors() error return

[Alan Horstmann]

Hi,

A user of the Portaudio library is reporting that from Alsa version 1.1.4 the 
function snd_pcm_poll_descriptors() can return -32 (Broken Pipe), and this 
fails an assert within Portaudio.  Earlier 1.1.3 does not seem to  show this 
issue.  For more details, see 
https://app.assembla.com/spaces/portaudio/support/tickets/268.

The Alsa docs don't mention any possible negative error code from this 
function - has the behaviour changed, or is it likely something else is 
triggering the difference?

Regards

Alan
