charlesttchen wroteI focus on Runeaudio 0.2 as it's closer to working. Now I can play music to analog output, airplay to USB DAC, but can't play any internal/NAS music file to USB DAC. Runeaudio turned to "Pause" when I pressed "Play". Here is my debug info (sorry for the long post, I'm to sure if I did it right)
Maybe it's just a matter of configuring/enablingthe right audio output for MPD as active, from your log seems the only active one are the lineout and HDMI on the Raspberry.
Try to logon onto the RuneAudio device via a remote session (for, example if you are running windows, download putty.exe on your local machine from the first hyperlink on this page:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Run Putty, enter the IP address of your Rune device and, when prompted enter,
root as username and
rune as password.
When the console session is established, please type
mpc outputs
You should be shown a list of outputs listed like this:
Output 1 (xxxxx...xxxx) is enabled/disblaed
Output 2 (yyyyy.yyyy) is enables/disabled
.....
if the USB output is disabled, try to type
mpc enable, followed by the output number you want to activate: e.g.
mpc enable 3, should you wish to enable Output 3.
At that stage the content in the library should be playing via MPD.
