no mp3 sound and it switches my default device [SOLVED]

I bought a Jensen USB turntable which came with Audacity software to convert records to mp3. I seem to be able to record records and export them as mp3 files. I can see that I am getting “levels” when it records in Audacity. But when I try to play the mp3 file back on Windows Media Player, I get no sound even though Windows Media Player tells me that there are “levels” in the recording. After I try playing back the mp3 file I find that I can no longer get sound from my computer at all. Checking, I found that it had changed my default audio device from “Speakers (RealTek High Definition Audio)” to “Speakers (USB-2 Audio Controller”). My control panel says both of these devices are “working,” but there is a green check by the USB-2 Audio Controller icon and none by the RealTek High Definition Audio icon. I click on the RealTek High Definition Audio icon and click “set as default” and I can normal sound from my computer again. But the mp3 file I recorded still has no sound. Any help much appreciated!

Sorry, forgot to include my information on my question before. I am running Vista and Audacity 2.0.0. I installed it from a software CD included with a Jensen USB turntable for converting records to mp3. I seem to be able to make recordings OK - I can see live “levels” during recording, and I can export the file to an mp3 file OK. But when I play the file back on Windows Media Player, I get not sound even though I can see the “levels” on the recording are there in WMP. After doing this I can no longer get sound from my computer at all, and I discovered that whenever I try to play the recorded mp3 file it has changed my default audio device from “Speakers (RealTek High Definition Audio)” to “Speakers (2-USb Audio Controller)” I have to reset the default audio device to get normal sound from my computer again. Any help much appreciated!

This is expected as per http://manual.audacityteam.org/o/man/faq_playback.html#usb .

You seem to have found the solution already but you may need to restart Media Player so that it realises the Realtek built-in sound device is now the default playback device and not the turntable.

I suggest that while the Realtek is the default playback device, you disconnect the turntable from the computer. Then when you reconnect the turntable hopefully Windows will not make it the default playback device.

Also please upgrade to the current Audacity 2.0.5: http://audacityteam.org/download/windows .
