I'm not speaking for the kernel team (which I'm not part of) but I own a X250 and wrote a page [1] about Linux support. I'm unsure what CONFIG_SND_SOC_INTEL_BROADWELL_MACH is supposed to be used for, but it's not needed for sound support on X250. At first sight this option looks related to Intel Smart Sound Technology (Intel SST) which looks to be a specific DSP for usages a bit like Siri on the iOS platforms. I don't think the CPU in the X250 has this technology, althought it might be useful for Core M Broadwell ultrabooks. In any case, loading the modules on my X250 doesn't do anything and don't show anything in dmesg either. So I don't say enabling it is bad, but I don't think it'll improve the experience on your ThinkPad. [1] http://www.corsac.net/X250/ Regards, -- Yves-Alexis
