Hi I'm using my pi with a PCM2704 USB DAC. It's working fine with rune audio.
You can get them on ebay for about $10 including shipping, it contains a TI 2704 chip 3,5mm analog out (stereo)
and Optical/Digital out.

While the DAC does play, the hardware volume controls have the "Always at 100" issue. Is there a setting that I can play with that will fix this? My Volumio 1.3 implementation worked fine with this DAC, although V1.4 didn't play nice with it.
I am attaching the DEBUG info, if that will help any.
Edit: after reading other posts, I found that the full DEBUG was supposed to use pastebin.com: http://pastebin.com/KYBC4zR8

rodgersan wrote:Hi,
Does it work if you use alsamixer to control volume? I got similar symptoms (permissions issues) and had it working changing mixer_device to "default" in /etc/mpd.conf. You may look for setting manually a different value for mixer_device.
Regards.
