Hi Pierre-Louis, Since I recently have been doing a bunch of i915 work I'm currently running drm-tip. This brought in this commit from next: https://cgit.freedesktop.org/drm-tip/commit/?id=c337104b1a16becc486fdc95d544c835b17021db This causes the hda driver to not bind to the audio on my Apollo Lake based laptop, and the asoc driver errors out with: [ 19.176417] skl_hda_dsp_generic skl_hda_dsp_generic: Unsupported HDAudio/iDisp configuration found [ 19.176428] skl_hda_dsp_generic: probe of skl_hda_dsp_generic failed with error -22 After which I get no sound and worse, the machine hangs on suspend. It seems to never reach its fully suspended state (the power-led never starts to fade on/off as it normally does when suspended). I've been looking through the Kconfig option and it seems that currently selecting SND_SOC_INTEL_APL makes little sense since there are 0 machine drivers for this setup ? I guess I can fix this by unselecting SND_SOC_INTEL_SKYLAKE and then during the manual platform selection not selecting SND_SOC_INTEL_APL, but IMHO we need to put something in place where the hda driver actually checks if there is a machine driver and if there isn't one then we should keep using the hda driver on the machine in question. Regards, Hans p.s. Merry Christmas! _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
