You might have to put albums in the internal memory, in MSC mode. You might even have to take them out of subfolders. It depends how smart your USB stereo is.
As for volume, definitely make sure you are not stuck with European region restrictions on volume.
But also remember, the Clip is only meant to power headphones, so it’s not putting a huge signal out of the headphone jack. When I connect mine to the AUX of my car stereo, I have to crank it up all the way and turn up the car stereo considerably.
And then when I switch back to car radio I have too remember to turn it down!
