What does "for full HDMI audio support" mean? What's the partial support? =) Tomi

The ASoC DAI component driver provides just that functionality. A machine, platform, and (in this case a dummy) codec component driver is also needed for a complete ALSA device functionality. Anyway, I look into Mark's suggestion of instantiating all the necessary component drivers from the HDMI driver. Best regards, Jyri
