I have started working on moving the HDMI audio part to /sound (http://www.spinics.net/lists/linux-omap/msg64477.html) and the relocation discussion has lead to proposing an interface to provide funtionality in DSS for displays that support audio (DisplayPort and HDMI, atm, http://www.spinics.net/lists/linux-omap/msg64744.html). I am about to send a set of patches to DSS for this and then have the audio driver use the proposed DSS functionality. > > Thanks a lot, > > Alex > > -- > To unsubscribe from this list: send the line "unsubscribe linux-omap" in > the body of a message to [email protected] > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
