Logitech S150 volume control unsatisfactory. Hello Community, I ordered the S150 because I want to use a USB connection. The speakers work, but I only have the choice between loud and very loud. Even with volume level 2, background music is much too loud. (Previously I used the Z120, which worked without any problems). I couldn't find a solution on the product page or in the forums. Does anyone here have a better solution? Many thanks in advance.
