Hi Clemens,
Thank you very much. but for the tlv320aic3x codec it works. tlv320aic3x device is also duplex device. and also after aplay calling, i can succesfully open the device for my codec driver. could you please tell me what i am missing and also why it is working for the tlv320aic3x device.
Thank you, Sreedhar.

Clemens Regards,
implementations; you should open the device twice. the device in full duplex mode. This is not supported by most OSS O_RDWR indicates that you want to use the same file handle to use

i found that if i open the device O_WRONLY and O_RDONLY mode it works. if i try to open the device using the O_RDWR mode it fails.
