Do loopback module stop the running pcm stream ?
Seem pulseaudio does not use snd_pcm_drop nor snd_pcm_drain, how can
the running pcm stream stop?
This is the beginning of the suspend function of module-loopback, so
obviously
sorry, the suspend function is in alsa-sink, not module-loopback ...
snd_pcm_close close is called instead of snd_pcm_drop or _drain (I did not
change anything here):
static int suspend(struct userdata *u) {
pa_assert(u);
pa_assert(u->pcm_handle);
/* Let's suspend -- we don't call snd_pcm_drain() here since that
might
* take awfully long with our long buffer sizes today. */
snd_pcm_close(u->pcm_handle);
