Much better :)
I no longer get the PlayBack overrun on PCM start. However, it appears
that "poll" or the snd_pcm_sw_params_set_avail_min (=4096) is not being
properly honored. With the normal alsa-lib, when the "poll" returns
snd_pcm_avail_update reports that space is available for 4096 frames.
However, in my initial testing, when running with SALSA lib, only about
100 frames or so are available when the poll returns.
I will examine this more closely.
