All of a sudden no sound

Audacity Help Forum Windows
1

I changed something in preferences and now I get this “Error while opening sound device. Please check the playback device and the project sample rate.”

I’m using a mbox3 as my audio device. Not sure what happened but now audio from Audacity and my browser is played back through the laptops internal speakers. Before, all audio came from the mbox.

I’m confused by some of the options listed in preferences. I’m attempting to playback wav files exported from Maschine at 24 bit 48 kHz. The problem began when I attempted to match these settings in audacity. Here’s my audio device info.

Any help is appreciated.

Thanks, I’ll take a look.

You could try choosing MME host in Audacity.

Audacity does not officially support MBox because that is intended for ProTools. Avid usually require you to download special drivers if you use MBox with other software. Did you do that?
