I’m recording cassettes and records with an external USB DAC. I’ve been doing this for some time with out major problems.
I recently upgraded to Mojave (10.14.2) and I cannot get any sound to come through Audacity. The input for both Audacity and iMac is set for USB AUDIO CODEC and output is set to Built-in. The iMac sound preference panel shows audio is present (bars are lighting up). However I cannot get Audacity to recognize it or play through. Same settings for Audacity. The line/phono inputs on the DAC are set properly as well. Audio files residing on the iMac play properly.
Thanks for any ideas.
