Hi Liam,
Since the stream is in SNDRV_CTL_POWER_D3hot state, all widgets are switched off. since the pop_wait is set , soc_pcm_prepare() will not turn on the widgets (or it will not change the stream state to SNDRV_CTL_POWER_D0). So actual sound will not come out.
Thanks Nobin Mathew

Any way calling close() before open() is not possible, i will restate it as calling close() before prepare().
Thanks Nobin Mathew

Hi Liam,
There are some players which will call snd-pcm_close() before any open call, i dont know why they are calling this. So in ASoC it will put the stream in SNDRV_CTL_POWER_D3hot and pop_wait equal to 1. This state will make problems in snd_pcm_prepare (i.e soc_pcm_prepare).
Trouble creating players and libraries are mpg123 and gstreamer library.
Can you give more detail about the problems. It's not obvious from your message. SNDRV_CTL_POWER_D3hot and pop_wait should not stop audio playback starting again.
Thanks
Liam
