Hi, I'm trying to link ALSA playback devices and DRM connectors. In other words, I'd like to be able to know which ALSA device I should open to play audio on a given connector. Unfortunately, I haven't found a way to extract this information. I know /proc/asound/cardN/eld* expose the EDID-like data. However by looking at the ALSA API (also: aplay -l and -L) I can't find a way to figure out which PCM device maps to the ELD. Am I missing something? If not, what would be the best way to expose this? - A symlink to the ALSA audio PCM device in /sys/class/drm/cardN-CONNECTOR? - A symlink to the DRM connector in /sys/class/sound/pcm*? - A DRM connector property? - Somehow expose the connector name via the ALSA API? - Expose the connector EDID via ALSA? - Other ideas? Thanks! Simon Ser _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
