That's progress; with the CODEC as master all the clocks within the CODEC will be configured correctly in relation to one another which will help with the noise - probably the MCLK rate does have issues like you say, with the CODEC as master pitch variations are a likely symptom. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
