I create a HDMI interface for TI davinic SoC. But capture file, my.wav, size is only 44 bytes after "arecord my.wav".
1. "arecord -l" display interface as:
root at c6a816x-evm:~# arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: hdmi [TI81XX hdmi], device 0: HDMI McASP Receive hdmi_sii9135-0 
Subdevice #0: subdevice #0
2. root at c6a816x-evm:/dev/snd# ls
controlC0 pcmC0D0c timer
I check sound/soc/davinci and see snd_pcm_lib_ioctl() is useless.
Could anyone please give me hint where to start debug?
