hi ,
u said that one file plays

does it mean tht if u supply only one file to the mixer(the above code ) itÂ plays or the file plays in another program?
chk the values before writting into the buffer if all are zero or all are same values no sound will be heard...
hope this helps

if the values written into the buffer are non zero and not are not same pls revert to me back
regs

What is your question ?

If it is "how it works", take a debugger and run the code to understand how it behaves.... Two clues:

Code:

// clear buffer
// has to be done because channels are mixed by adding their values
// to each other

Code:

*buf++ += sample;
