I have two System76 PCs: Leopard Extreme and Lemur Ultra Thin which I purchased in late 2012.
I have the HeadRoom Ultra Desktop Amp with DAC and desktop power supply along with a Meridian 808v5. I use a Cardas Clear serial buss USB 2.0 cable to connect my System76 Leopard Extreme to my Meridian 808v5. It shows up as the Meridian 808v5 USB DAC in Ubuntu 12.10 64 bit.
You'll need to download and install DeaDBeef and use the ALSA sink at hw 0,1 to get bit-perfect audio:
http://www.head-fi.org/t/561961/bit-perfect-audio-from-linux. See that Head-Fi thread about getting bit-perfect audio playback in Linux using various FLOSS music players.
Clementine can do the same thing if you use the clementine development trunk:
http://www.clementine-player.org/downloads. Scroll down to this section:
There's also an Ubuntu PPA for these development builds:
Code:
[size=12px] sudo add-apt-repository ppa:me-davidsansome/clementine-dev sudo apt-get update sudo apt-get install clementine[/size]
You can configure Clementine to choose the GStreamer output plugin manually or automatically.
I'd recommend that you choose Clementine development trunk because it's slightly easier to configure to output bit-perfect audio. I have a Benchmark DAC-1 Pre on loan from an authorized dealer in my listening room at home right now and I am using my HD Tracks 24 bit 192 kHz albums to output FLAC loss less high resolution audio files to my Benchmark DAC1 Pre at 24 bits 192 kHz resolution using Clementine development trunk with the GStreamer output plugin set to automatic when it is directly connected to my System76 Leopard Extreme using my Cardas Clear serial buss USB 2.0 cable. Your results will vary.
Remember, this is GNU/Linux. Things are bound to go awry. You may not get any sound output if you experiment and you're on your own.
I am an Ubuntu certified Linux systems administrator and information assurance manager at work.
Try out the suggestions in the first Head-Fi thread that I posted with the other music players and see if you get the results that you want before you try Clementine. If all else fails, try Clementine development trunk.
