The company on Wednesday posted an underlying operating loss of $4.5 million, against a profit of $1.5 million for the same period a year ago, on revenue that dipped to $42 million from $56.1 million.

Chief Executive Mike Hickey said he expected the company to resume its growth trajectory in the second half of 2014 as customer phone inventories unwind and new products are launched with its next-generation audio technology.
