I got the DAC+ to partially work with Raspbmc (see my other post) but when it works I get the following problem: the DAC+ is connected to my amplifier, a recent model by Onkyo which has always worked fine. The only way in which the sound gets through is by setting Raspbmc volume almost to the minimum and to use the amplifier's volume control. When the music plays the quality is perfect but when it doesn't it results in some white noise (I'll try using a ground loop between the DAC+ and the amplifier). Otherwise I get just noise (if I put Raspbmc on a higher volume and the amplifier on its normal level). Is this normal? Do I have to configure something in alsamixer to have it work at a normal level?
Thank you in advance!
