In my application i am closing and reopening my device toconfigure some hw_params for audio frequency change.
You should just set new hw_params on the same device.
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}
IIRC this could happen when using dmix on some old alsa-lib version.
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.
Thank you very much for keeping the error code a secret.
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}
Stop the device first.
