>dmix not stopping
I'll correct: plug:dmix can stop and enter XRUN given an appropriate
stop_threshold.

>[#samples < period never start] Have you seen this happen?
Definitely, in both XRUN and free running modes. plug:dmix starts only once
written the frame #period_size, one by one or en bloc. snd_pcm_start or
set_start_threshold won't change anything.

plughw is different and starts as soon as the first sample is written.

>one more try
Did you try out my render tests from bug #27937? It's not my newest, but still
useful. In particular, you can change the sleep(350) to test underrun behaviour
as well as change "default" to "pulse", "plug:dmix" or "plughw:0" in
mmdevdrv.c. I can't apply your code yet because my ALSA machine is not sync'ed
with git now.

>       TRACE("PCM state: %u\n", snd_pcm_state(This->pcm_handle));
This looks like left over from debugging. To make it useful, please add
avail_frames and possibly padding.

>Initialize: snd_pcm_hw_params_current after snd_pcm_hw_params
is superfluous, This->hw_params is up to date. ALSA does not behave like a OO
factory.

>MinimumPeriod = 100000
I'd make it smaller than DefaultPeriod, e.g. 5ms.

>this call seems to be required to get an accurate snd_pcm_state
I observed the same requirement for snd_pcm_delay

Do you think you need
snd_pcm_state(This->pcm_handle) == SND_PCM_STATE_XRUN
My tests show this test is superseded by avail > alsa_size. I.e. after XRUN,
avail is larger. Not cross-checked with PA.
