Thanks for the answer. Unfortunately, the hints on the page you linked didn't work. The firmware on that page is already included in linux-firmware (unless I'm missing something, of course). I tried compiling it in the kernel, but with no result. I believe the problem is something other than missing firmware, because I see no messages about failures to load firmware in dmes. I just noticed there are some audio-related messages in dmesg which I hadn't noticed before: [drm] HDaudio controller not detected, using LPE audio instead cht-bsw-rt5645: ASoC: CODEC DAI snd-soc-dummy-dai not registered cht-bsw-rt5645: snd_soc_register_card failed -517 I don't know whether they're significant or they're spurious messages caused by my including every possible sound card drivers in the kernel. I fear you're right about this Transformer not being linux friendly: I just found out that it doesn't recognize the power button, either. I think right now I need a break from this machine: I've alread spent about three days working on it and I have other things to do. I'll try to rebuild a kernel from scratch in a few days; in the meanwhile I'll use it as it is. Thanks again Stefano
