This is way out of my league and I hope I'm in the proper section of the forum.
I'm just wondering what signal I'm dealing with on the new Sansa Clip that I picked up.
What are the signals accessible from the mini usb b-socket? Is it necessary to have a USB compatible device to process them? I'm wondering if it's possible to use the raw signal as input to an amp? I realize I can use the headphone jack, but I was just wondering if it was possible to make a single connection to a home stereo using only the USB outs.
In other words (if necessary), a cable connected to the system via bare wires into a mini usb type-b plug that will simply plug into the MP-3 player.

I don't know anything about digital audio either, so I never post in this area of the forum. However, the signal from the mp3 player is surely digital, and would have to be converted to analog before sending it to an amplifier.
Well USB signals need a special USB IC to interface.
But i guess what you are talking about is the 11 pin miniusb connector that is sometimes used on mobile phones or pocketPCs to provide various features over it while still being standard miniUSB compatible. Those do have a direct headphone output on them however these connectors are difficult to find and you need to find a pin out somewhere (might not be very standardized)

No. The USB connection more or less just shares out the contents of the flash memory as if it were a USB memory key or hard drive, and requires something intelligent like a computer to transfer data. Some A/V receivers and car decks have USB ports on them that support USB memory keys, and will presumably access compatible MP3 players as well. And there's various media player boxes, like the Western Digital WD TV that play content off USB storage devices. You could do much worse than pick up a WDTV box; it's got S/PDIF out for audio (and digital surround), plus HDMI for high-definition video. (It'll even play Blu-ray and HD-DVD quality content.) Maybe the only real flaws are that it requires a video monitor connected (no internal display), and doesn't support HDMI 1.3 or SVideo.
Yes thats true that most such players simply act as a USB Mass Storage device that shows the internal memory but its not always the case. If you closely look in to the connector you can see if its a 11 pin one(Normal miniusb is 5 pin) in that case audio could be provided on it (If you can get the 11 pin male side connector and the pinout) Some devices even have headphone out on a standard 5 pin miniusb by using a MUX to switch between the USB controller or the headphone amp.This is mostly only done on devices that have no other connectors (I think the popular ipod nano dose this)
But anyway if there is audio on the usb connector it will be hard to get to.SO if you have a standard lineout jack use it.
