I recently posted a patch on the HDMI CODEC to interface a HDMI transmitter http://mailman.alsa-project.org/pipermail/alsa-devel/2014-October/082745.html and I saw only a few dependencies between the 2 subsystems: - the CODEC must know the transmitter parameters (DAIs - static -, audio constraints - dynamic -), - the CODEC must alert the transmitter on audio start and stop. I don't think that stopping audio streaming on HDMI disconnection is useful. I even let audio streaming start when the HDMI cable is disconnected. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
