Rather noisy as stated in the comments. But it is still nice (rather sober but on the lower valve DVD there is a little curve (is the best seen in the picture:. [...]) It's not much but it is not 100% sober. To return to the sound that occurs when running in background (import drivers, music) for films I have not tried it yet; I use it only for that so it does not bother me; especially for this price. Note that the output rate is very good. On iTunes with my old PC I reached the 8x - 13x. With that it is up to the 40x -45x.
