Hello All,

A) In my application i am closing and reopening my device to configure some hw_params for audio frequency change. Close of PCM device is success, but reopen the same device fails

I get an below error snd_pcm_open() FAIL with return value -16 {Device or resource busy}

How can i avoid above error. {I tried putting usleep between open and close but doesn't work for me}

B)

I have even tried to configure the HW params in run time to avoid above closing and opening of device. But run time HW params configuartion failed. Is there any way to change HW params at run time ? {My PCM device are in RUNNING state and i want to change HW params at run time}

Thanks and regards, Irfan
