I'm running Arch with a 4.3 kernel[2] with patches[3] for wifi stability. So far, the drivers appear to load, but produce the following dmesg output: > [ 5.579629] baytrail-pcm-audio baytrail-pcm-audio: ipc: error DSP boot timeout > [ 5.579841] byt-rt5640 byt-rt5640: ASoC: CPU DAI baytrail-pcm-audio not registered No devices are listed in the output from 'aplay -l' (presumably due to the above): > $ aplay -l > aplay: device_list:268: no soundcards found... I've tried alternative firmware[4], but still get output like the above. The system is a Baytrail compute stick (similar to Intel's Compute Stick) and supports both HDMI audio and analog jack. There appears to be a patch from Intel[5], but it's monolithic and targetted toward a much older kernel. It's also a bit unclear if any of the patches were ever upstreamed. Am I doing something obviously wrong here? If not, are there any patches I can try to get this thing working?
