IMX53 QSB: Error opening sound device -blog archive

Discussion created by MahadevaSwamy L on Oct 19, 2011

Hello,

I am trying to open my module where there is an Audio output,  but I am getting this following error and audio is not heard.
We are using IMX 53 Quick start board.

 

I need libasound.a file for my compilation. I am using libasound.a file which is given by demo package of IMX53 QSB. Please provide the libasound.a for IMX53 QSB and source code for host, so that we can cross compile.
