[alsa-devel] Assert in pcm_params.c

Hi,

I am trying to assist in a case that is getting this assert:-

pcm_params.c:2249: snd1_pcm_hw_params_slave: Assertion `err >= 0' failed.

and wondered if anyone could shed some light on what is likely to cause that, and whether it indicates an underlying fault?

The system (not mine) runs Linux Mint 13 (kernel 3.2.0) with PulseAudio, and we are debugging weird behaviour during Portaudio initialisation. It is struggling to get consistent access to the Alsa devices, often retrying many times.

Any pointers would be appreciated.

Thanks

Alan
