ALSA documentation (which may be out of date) says that the hw_params callback can be called multiple times during stream setup. Do we want to be repeatedly programming the HDMI infoframe with different settings, potentially confusing the attached device, or would it be better to do it slightly later (in the prepare callback) after the parameters have been fully negotiated? -- FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
