Hello,

Tinyplay utility fails to play a sample audio wav file when followed with the below steps on Android platform,

 

evk_8mq:/storage/emulated/0 # tinyplay testw2.wav

Unable to open PCM device 0 (cannot set hw params: Invalid argument)

 

No parameters are observed under ctl,type,num,name and value fileds.Tinymix displays the following content 

evk_8mq:/storage/emulated/0 # tinymix
Mixer name: 'wm8524-audio'
Number of controls: 0
ctl       type      num       name       value

 

 

Can you please provide me some inputs on this?
