The scan audio logic only enables multiple audio standard detection if the userspace application tells it to do.
No: the _first_ scan is done on the driver init. It is a multi-standard one, and a long one, too. Do we need it at all? It seems to me the results of that scan are not even used, or what am I missing?
A first scan at driver's init can be removed, IMO. The thing is that newer versions of udev will open the device, to do a VIDIOC_QUERYCAP. Not sure if this will wake up the tvaudio kthread to do a scan.
