[PROBLEM] Audinst HUD-mini ... no sound :(

[HolyK]

Hello all,

i am planning to build a small home theater boxie for my new TV so i am thinking about Raspberry PI 2. Before i do this i borrowed an old version of RPI B from my colleague to do some testing just to try several distros and to become a friend with it. I've ended up with xbian which i like but now i'm stuck on making an USB DAC for my audio equipment to work :/

I have Audinst HUD-mini DAC which is a HID device and does not require any specific driver. I can see the device properly recognized under System -> Audio Output as "ALSA: Default (Audinst HUD-mini Analog)". When playing a video the DAC led starts blinking which signalizes that there is a signal processed but no sound actually comes out :/

So the question is what is the cause? The DAC should not be underpowered since i've set "max_usb_current=1" in the config.txt and the DAC seems to be "alive" (orange LED="standby" and its blinking green while playing="playback"). Maybe the audio is not properly passed to the DAC ? I found some reference HERE that Volumio distro worsk with the higher version of the Audinst DAC, so it might be only some software thing which causing this?
