I have a HRT HeadStreamer, a USB soundcard: http://highresolutiontechnologies.com/headstreamer When using PulseAudio with ALSA backend, I only get sound when the volume is above 100%. Looking at alsamixer while adjusting the slider in pavucontrol it is 0 until the slider is at 100%, then it jumps to 99 in one step. I've tried Pulseaudio 1.1 and 2.0 in Archlinux, and 1.1 in both Fedora and Ubuntu with the same result.
alsa-info output would be useful
