Unfortunately, this has caused a regression. The SST and SOF driverscannot both be enabled for the same Intel platform in the kernelconfiguration, according to Intel.https://bugzilla.kernel.org/show_bug.cgi?id=204237#c15

As described in the bug, this change causes a loss of sound on the IntelBroadwell platform (and even significantly degrades system performancewhen attempting to play sound).
