Recommendation from Lennart Poettering:
In ALSA_OpenAudio(): instead of setting period_size+n_periods OR
buffer_size I'd recommend copying the hwparams stuff before you do
this, then first try period_size+n_periods, and then apply it with
snd_pcm_hw_params() and check if that works. If it didn't you should
take the copy of hwparams and try setting buffer_size and apply that
via snd_pcm_hw_params() and check if that worked. And if that failed
too, then take the copy and don't apply neither period nor buffer
settings and see if that works.
