Hi,
I have developed a audio driver, the audio ic is interfaced with the TI DM365 processor MCBSP ports.
I am working with the 2.6.32 kernel.
I am able to play the audio using the aplay command. but when i try to open the device using /dev/dsp i am getting the -ve value. it fails to open the device.
when i check the
>> ls /dev/dsp
it is available in the device directory.
I have enabled the Sound OSS related options in the kernel menuconfig. with the same options i am able to open the device for the tlv320aic3x device on DM365 leopard evm.
Could anyone please suggest where i am doing wrong? and help to solve this problem.
Thank you, Sreedhar.
