I don't have 1500, but I assume they run like the others--
They put the phones and mic connections on the radio mostly for convenience. Many people like a traditional rig-type audio connection. They run the digital audio paths back to sound interface chips in the rig box to make this convenience. It is passing it back to the rig in digital form on the usb path (1500) or firewire (3000-5000).
Can you use your computer audio? SURE! You must use the Virtual Audio Cable (VAC) connection in PowerSDR. You also need Virtual Audio Cable software that creates a virtual audio cable connection between the VAC interface in PowerSDR and your computer mic and speaker devices. That is it. Simpler than it sounds.
You will love it. You can hook those virtual audio cables to anything! Hook to skype and run remote. Hook to any of the digital software for rtty, psk31,etc and good to go. No separate audio boxes or anything.

I've been playing with my new Flex-1500 for a couple of days now. BTW, plugged it into my laptop, installed PowerSDR (and VspMgr, and VAC, and MixW)... DONE! Worked first time. I took all the defaults. No pops, no clicks, no problems at all. With all of 3 watts I had PSK QSO with someone in Panama. I already love this radio. But I have some sort of conceptual gap in my understanding that I'm SURE somebody can clear up for me: 1) The signal is filtered and demodulated by PowerSDR in the computer... so why is the "phones" connection on the front panel of the radio? How does the audio GET there (back across the USB connection)? Is there a way to use my laptop's sound card and speakers to hear the radio audio? 2) Similar to the above, but for the microphone connection: The mic connector is on the radio, not into the computer. Does the mic audio travel back across the USB from the radio? Is there a way to use my laptop's microphone as input?
