NOVATO -- Software maker Sonic Solutions (Nasdaq: SNIC) reported its second-quarter net loss grew by $2.3 million from a year before, while net revenue decreased by 3 percent.

Second-quarter net revenue of $25.3 million, down from $26.1 million reported for the quarter a year ago.

“Our second quarter results were in-line with our expectations and reflect the strength of our value proposition to our customers,” said Dave Habiger, president and chief executive officer.
