    Which audio card is it? Did you download the lastest drivers? Did you update the audio card firmware? Some weird stuff (random reboots & kernel panics) happened to me with the audio card and Yosemite until I updated its firmware. Now it works rock solid. Do you have any other internal audio devices installed (like Boom, Soundflower, etc)?
    And a "stupid question" but: did you configure the audio to use the audio card as the system output? Sometimes the simpliest thing...

    As it seems (doing a lil of research) you're right, there's no drivers for Mac (nor firmware updates) of Lexicon Alpha (a bit weird because all the rest of Lexicon sound cards have mac drivers). Despite that, in their official page they say that Alpha doesn't need drivers. You should contact Lexicon in their main page to see if they can provide a solution. It might be some compatibility problem with Yosemite. As I said before, I also had problems using my Roland Octa-Capture with Yosemite until I upgraded drivers & firmware, so Yosemite (despite being similar to Mavericks in the core) can mess up audio devices.
