Bankrupt consumer electronics maker Sonicblue Inc. on Wednesday sold its ReplayTV service and Rio portable music systems to Japan's D&M Holding, effectively ending its run as a digital audio pioneer and its threat to major media companies.

Japan's D&M Holdings Inc., parent of high-end audio equipment makers Denon Ltd. and Marantz Japan Inc., won a bankruptcy court auction to acquire Sonicblue's ReplayTV television recording service and Rio portable audio unit for about $36.2 million.
