broadcast audio processing frrrrrreak

[quote author=”irish”](2) What general settings would you suggest for someone listening to music or watching videos, with a realtek soundcard, and speakers that probably didn’t cost more than 2o euro euros, on a laptop and desktop.[/quote]
Whatever sounds best in the acoustic space they are in, from the preferred listening spot. It depends on what videos you’re watching too. If you’re watching movies and standardized TV productions, then you know pretty well what to expect of the input, and you can get by with a lot less processing than you would probably want on something like random YouTube videos.

[quote author=”irish”](3) when playing something, after a while the program would make an odd noise, spluttering might be the best way to describe it. Then afterwards, i would hear crackling noise when playing something. I think though the format, of the file might have something to do with it, as it only seems to happen on some files, and then, not on all those type of files.[/quote]
It could be that you don’t have enough buffering or a "fluid" enough combination of length/count. Sometimes a combination that results in a longer total buffer can be less stable than some other combination. It also could be that you have a naughty driver on your system that has DPC latency spikes. Try disabling all networking and usb devices in your device manager, and see if that solves the problem. There’s also a few DPC latency checking programs around the internet, if you want to track down the culprit.
