Hi, Dear developers
I have a question about ALSA plug-in for PA.
ALSA's snd_pcm_prepare will go into ALSA plug-in for PA, and call pulse_prepare which will first pa_stream_disconnect, and then pa_stream_new.

You know, the pause of audio device of many Media framework will call snd_pcm_prepare, take Helix for example.
If Helix uses ALSA audio device, Helix will execute pause of a pa_stream as "destroy pa_stream then create new pa_stream".

The question is: Is it possible to let pulse_prepare do not destroy-and-create pa_stream?
Thanks a lot!

Best Regards, Zheng, Huan(ZBT)
