Assume that the bug is USB audio core changes, the following 8 commits are relevant: 1045f5f1ff0751423aeb65648e5e1abd7a7a8672 9355b60e401d825590d37f04ea873c58efe9b7bf a74f8d0aa902ca494676b79226e0b5a1747b81d4 9902b303b5ade208b58f0dd38a09831813582211 9a737e7f8b371e97eb649904276407cee2c9cf30 2be79d58645465351af5320eb14c70a94724c5ef ac5e2fb425e1121ceef2b9d1b3ffccc195d55707 Could you try to revert from top to bottom one-by-one, and check which one makes things working again? The most suspected one is 2be79d586454 (one before the last, a big change), but who knows... thanks, Takashi
