Right, so the only platform I have out of that (as I said above) is SDP4430. And as I've already said, it does *not* appear to support any audio of any kind: root@omap-4430sdp:~# insmod snd-soc-twl6040.ko root@omap-4430sdp:~# insmod snd-soc-omap.ko root@omap-4430sdp:~# insmod snd-soc-omap-mcpdm.ko root@omap-4430sdp:~# insmod snd-soc-omap-abe-twl6040.ko root@omap-4430sdp:~# cat /proc/asound/cards --- no soundcards --- and that's with HDMI audio via DSS enabled. So, it does *NOT* appear to support any kind of audio. (If it does, software support for it is broken when built as modules.) How do I get audio support working on this platform? -- 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
