1.3 Check sound device drivers and firmware 1.4 Check PCI card or external sound device settings and connections 2 Why do I get "Error: not well formed (invalid token) at line x"? 3 Why do I get "FFmpeg Error - Can't open audio codec 0x15002?" http://manual.audacityteam.org/man/faq_errors.html 4 Why does the computer reboot or show a blue screen message when I launch Audacity or play or record? 5 Mac OS X: Why do I see "Critical Nyquist files cannot be found"? 6 "I found a bug!" or "Feature X is not good enough or is missing!" now what? 6.1 Bugs 6.2 Feature Requests Why do I get "Error while opening sound device"? This error message asks you to check the recording or playback device settings and the Audacity error opening project sample rate. If the message mentions "recording device", it means there's a problem with your Audacity, operating system or sound device recording settings. If the message mentions "playback device", it means there is a problem with your playback settings. Either message can suggest a problem with the drivers of the sound device, or possibly that you are asking the device to do something it cannot do. For example you will see this error if you attempt to append record to more error opening sound channels than your device supports, or if you try to overdub on a device that can either record or play back but not both. The recording device message most commonly occurs on Windows Vista, Windows 7 or Windows 8 when one of the sound device inputs is not properly enabled or otherwise cannot respond to Audacity's request to start recording. Check Audacity Settings It may be a good idea to try to play or record after checking or changing each of the following Audacity settings. Sometimes a project rate change is all that is needed. Set the project rate bottom left of the Audacity window to the standard rate of 44100 Hz (or if your soundcard only supports a particular rate such as 48000 Hz, set the project rate to that). Help > Audio Device Info... should show the rates the device claims to support. Try turning off Transport > Software Playthrough (on/off) (this should never be enabled if recording computer playback). Try turning off Transport > Overdub (on/off) because recording while playing could stress your sound device or computer. If this solves the problem, read the Wiki pages Updating Sound Device Drivers and Managing Computer Resources and Drivers for advice on how to make your sound device or computer more capable. Check in Device Toolbar that the playback and recording devices are correctly and explicitly selected. On Windows, don't choose "Microsoft Sound Mapper" or "Primary Sound Driver" which point to the curr
