and trying to record and play the audio file using aerecord and aplay command
It is displaying proper statements but it is neither recording nor playing…Only tic tic sound is coming for a very short periodx
I am able to play S-Video too but Audio dosent work. I tried to copy and play the file on Linux PC also but the same problem i.e; no Audio Output.
What is the 1st step Make sure whether your player is running or not?
