Windows 7 Home Premium - all updates
Audacity 2.0.6
Downloaded EXE file from SourceForge
I updated to 2.0.6 from 2.0.2 and I get an error at start-up: “Error Initializing Audio. Could not find any audio devices. You will not be able to play or record. Internal PortAudio error.” And in Preferences there is nothing at all showing in any of the four drop-downs. My audio devices showed up fine in the previous version and I had just completed a project and exported an MP3 file the day before. What happened? How to fix this?
Both playback options are enabled: Speakers and Headphones (default) and Communications Headphones. Recording options are enabled too. Other software is using audio okay.
Thanks. Presumably the same problem that fails the advanced checks in dxdiag causes problems for PortAudio.
I suggest you open Windows Device Manager. Expand “Sound, video and game controllers”. You may find yellow exclamation marks there. I suggest you uninstall all the audio devices, don’t reboot, go to the HP web site then download the latest Windows 7 Home Premium 64-bit audio drivers for your HP Pavilion dm4 Notebook PC. Install the drivers then reboot.
