Maybe I didn't explain myself well. I'll try again. I would like to listen to CDs with jriver as the player. But since the Minix (my PC) doesn't have an internal CD player, I have to add an external one. Is it possible to use the Philips?
Sure. You can read CDs with the BDP9500, send the audio to your Minix with the Hifime UR23, record that audio using Audacity, Audition, etc, then use JRiver to play back this audio on the Minix's built-in DAC, or on an external DAC.
This process would be greatly simplified by a CD/DVD/BD Reader that has a USB output.
That way, JRiver should be able to read the audio directly from the CD and you could skip the UR23 and Audacity recording step.
