Audio out via USB

Postby Need4speed » 26 Apr 2009, 12:57

Hi Guys, I am trying to rig my laptop up to an amplifier to play mpeg music through an external amplifier. My kit is a Dell XPS M1530 (with no external sound card) and my amp is a PA with a USB module. I have it connected with a USB A/A (male/male) lead but nothing comes through.
Is there something I need to switch on to output audio via USB or do I need to download some software or something?

Does the laptop detect your amp as an external device when you plug it in? You may need to set the output in your sound options to whatever that device is called.

No it doesn't detect the amp and it didn't "install new hardware" like it normally does when you add a new USB device. Where do I go to force it to see the new device?

If you go into Device Manager it should show an unknown device, you can right click and scan for hardware changes although to be honest from what you've said it doesn't sound like the PA is supposed to function in this way with USB unless you've had a machine connected like this before?

Normally as Binnsy has said with an external USB soundcard it should pop up immediately that it's found new hardware then ask for a driver or load its own. After that it's simply a case of changing the default sound output to the new USB soundcard as opposed to the onboard one.

Here's the link to the system http://www.skytronic.co.uk/product/index.php?s=170.298 it says on the site
# USB port allows MP3 audio files to played

I think you're using the USB port the wrong way, it looks like you plug in a USB mass storage device and the PA will play the files from it.

I think I see what you mean John - if this is the case I was misled at the showroom because I specifically asked the question and was told that all I had to do was connect my laptop via the usb and it would play my discs (I want to use it for home bbqs etc and karaoke).
By "mass storage device" do you mean an mp3 player like an Ipod? I did try to connect my iphone to it but nothing happened.

By mass storage it would have to be a flash drive, do you have a headpphone socket on your laptop? If so you could get a 3.5mm to 2 phono lead and plug into an aux or CD or tape input on PA, you could then play through it that way.

That's exactly what I've done so far and that part of it is working perfectly. I could use an SD/MMC card however I did buy it for the USB connectivity - so exactly what is the usb socket for then would you reckon?

I imagine the USB socket is most likely for playing files of a USB pen drive.

That's the way I read it, given the M1530 I'm sure has a reasonable line out what was desirable about a USB option?

OK, I've tried that and that appears to be the answer, a bit disappointing that it doesn't do what I was told it would, but there we go - thanks to everyone for the advice.
