Hi, Is it possible to use a Rasp Pi 2 + Hifiberry DAC as a usb audio device and not a streaming player? I want to use it at my computer running the music program on my computer going out via usb into the pi and the hifiberry dac analog out to my speakers.

I bought the pi2 & hifiberry DAC+ not realizing Volumio would not work this way and that I did not want a streamer but a USB audio sound card -- PC soundcard replacement.

I don't need recording just playback.

thanks, stephanie

  in theory it's possible for sure. but you will need to make software on both sides, raspberry and PC. loads of work and compatible with nothing. I think you are better of buying a good USB sound card.
  
  or.. not the solution I know, use the pi2 as a PC. I have been told a version of windows 10 will work on it.
  
  what music player do you want to use?

  I don't think this will be possible at all as the Raspberry Pi USB port can't act as a slave. Windows 10 on the Raspberry Pi is not what you know as Windows 10. It is a stripped down version without a user interface. You can't run normal Windows programs on the Raspberry Pi.

  USB would be on the PC side, not the raspberry side.
  
  thats good to know about windows 10, its not a good idea to use a pi as pc anyway.

  Hi, I was hoping it could act as a low latency USB audio out for editing with Audacity or even Izotope RX. I use Foobar as a music player. thanks, stephanie

  Again its kinda reversed engineering. if you would succeed, it wouldn't be as effective as a cheaper USB or internal soundcard. Also using it for editing even makes it more difficult.
  
  Personally I look at my raspberry pi's as devices I use so I don't have to use a PC (all the time).
  
  I was hoping to point you in the direction of a similair music player for pi, but I'm not familair with foobar music player sorry. I'm sure you'll find a good purpose for it though!

  Raspberry Pi do have OTG usb port. Thus, in theory it can be a slave to host PC. The problem is that raspberry pi needs a gadget driver as UAC DAC. I'm not sure if there is gadget driver. For host PC, Linux supports UAC1 and UAC2. No drivers are needed for your PC. The only part is unknown is gadget driver in raspberry pi.
