Praveen,

Can you please check the list of playback devices supported on you board.

The following command will display the list of playback devices.

# aplay -l

ex: output

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: EVM [TI81XX EVM], device 0: AIC3X tlv320aic3x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

card 0: EVM [TI81XX EVM], device 1: hdmi HDMI-DAI-CODEC-1 []
Subdevices: 1/1
Subdevice #0: subdevice #0

Once you got the list of devices you can try the aplay command with proper argument for the specific device.

# aplay -Dhw: X,Y <audio file>

X - Subdevice

Y - device

Ex: aplay -Dhw:0,0 <audio file> will play through the AIC codec

Ex: aplay -Dhw:0,1 <audio file> will play through the HDMI codec

Thanks for your reply Deepu Raj,

have tried with the command : $aplay -l

it displays like (aplay: device_list:200: no soundcards found...)

what could be the problem.?

Praveen,

The issue is because there is no sound device detected by the Linux ALSA layer.

Are you using the binaries from the DVSDK release package ? are you using any costume board or a TI EVM ?

Praveen,

Can you please provide the complete product name of the EVM ?

Ex: DM365 , DM6467, DM8168 etc..

Are you using the prebuilt kernel image from the DVSDK release package or its costume build one ?
