Hi,
In the CAudioOutLinuxAlsa::_SetDeviceConfig() method, if there's an error before the snd_pcm_hw_params_get_period_size(hwparams, &period_size, 0) call, it will skip this call.  When this call is skipped, period_size is zero.  When the calculation for start_threshold started, a floating point exception is thrown because of a divide-by-zero problem.

Could someone apply a quick patch for this?  I currently don't have commit access.

Thanks,
--Khanh
