Ok, so this is with an explicit matrix provided. > Could you explain what you mean by "the actual layouts are necessary to build > the matrix"? When the matrix is not explicitly provided, lswr computes it. For that, it needs the channel layout, because you do not mix a rear channel the same way as a subwoofer. This patch absolutely needs to be tested under these circumstances too. Regards, -- Nicolas George
