Audio glitch when playing on Qemu

[sudarshan bisht]

OK, I am not much familiar to Qemu, but what is the emulated processor speed
in your case ?

It may be a performance issue , If possible you can try running top command
when you play your file and see the CPU load. If CPU load is very high then
there is a very little chance to do something except reducing the video
resolution or fps to some optimum values and then running it.
