Hello Mr Munir, Yes, GNU Radio will work with a 12 core CPU. Problems with the audio sink are usually a clock crossing issue. Your sound card is running at a slightly different sample rate than whatever the source of your samples is. Do you have a throttle block or a piece of hardware such as a radio which is the source of the samples GNU Radio is processing?
