Dear Clemens,

Thanks a lot for your information, It is really understandable for a newbie like me

As you suggested, could you please provide me some sample application links without using dshare plugin , ie., using the two channels ie., left & right directly

So that I can reduce the CPU consumption drastically

Thanks  a lot for your prompt support w.r.t this thread once again

Kindly do the needful as early as possible

Many Thanks in advance again

"This device" is the virtual device that is defined.
The slave device is the device whose name is specified with "slave.pcm".
