Hi All,
We are writing small application on TI's DM6446 evaluation board.
I am facing sound related problem i.e., with /dev/dsp.
When we are playing some .wav file using na_play ,I could hear the sound for a
longer period without any problem.
But from a C routine when we are executing a shell script using system call()
to play a .wav file continuously for a period of time in a for loop.
After some time around 2-5 min sound goes off, but shell script is still being
called by c routine and even after reboot sound doesn't come up.
Finally we have to do a hard reset to reboot the system to correct this sound
problem.
I don't find any error messages in dmesg.
Even command fuser -v /dev/dsp shows only my application name.
Sample code:
C routine:
for (int i=0; i< 1000; i++ )
system ("./na_play tem.wav");
na_play is the player in current directory and
tem.wav is the .wav file to play.
Please help to find out actual problem and solution if possible.
Regards,
Santosh
