I'm running CrossOver 15.0.0 on Ubuntu 16.04 using a SoundBlaster Tactic 3D Sigma headset (speaker/microphone combination), run via the USB connection.
After using 7z to extract setup.exe from Setup.exe, I got Rosetta Stone to install, update, and activate. However, it does not recognize that I have a microphone installed. It does output sound (voices repeating words from Lesson 1). I installed Audacity into the same CrossOver bottle. Audacity recognized the headset without any adjustments. I was able to record, play back, and save audio files through Audacity. Rosetta Stone still does not detect the headset microphone.
Any suggestions for getting Rosetta to detect my microphone would be appreciated.
