Losing Sound in All Programs

I am using Audacity v2.0.5 in 32-bit Windows 7 SP1 to create clips from mp3s.
I downloaded the executable and installed yesterday and have only come across one problem:
Sometimes after I trim a selection and save as a new mp3, all sound is gone from my machine. The taskbar and volume controls are still active. I checked in Audacity, Chrome, and VLC and no sound is coming through. To fix this, I go into Device Manager and disable then enable my audio device (High Definition Audio Device) and all is well. There are no additional USB recording or listening devices in play.
This does not happen every time, but has occurred twice in the last hour.
I am assuming a bug and apologize for asking an answered question. I wasn’t able to find this problem via search.

Thank you for any help. It’s not a showstopper, just something I find worth mentioning.

Can you try: http://wiki.audacityteam.org/wiki/Updating_Sound_Device_Drivers .

It is possible you need to correct the drivers you have for this Realtek device so they are the latest ones supplied by the computer or motherboard manufacturer.


I’m going to guess it’s a driver problem.

Does this only happen with Audacity? If so, it could be some interaction/conflict with another “background” application, but that would usually be related to a driver problem too.

If updating drivers doesn’t help, you might try a different soundcard. The new soundcard with either have it’s own drivers or it will use the Windoew-supplied drivers. I have an inexpensive USB soundcard that I bought just for “troubleshooting purposes”. You can find USB souncards online for less than $5 USD, although I didn’t buy the cheapest one I could find and I think I paid closer to $20.

to create clips from mp3s…

… and save as a new mp3.

Off-topic - MP3 is lossy compression and when you open an MP3 in a “normal” audio editor (such as Audacity), it has to be decompressed first. If you re-save as MP3 (or other lossy compression format) it goes through a 2nd lossy compression step. You don’t necessarily hear any quality loss, but it’s something you should be aware of.

There are special MP3 editors such as [u]mp3DirectCut[/u] (FREE!) that can do limited-basic editing without decompressing.
