Revision 1385, 3.8 kB (checked in by ppalmers, 12 years ago)

Implement a mechanism to disable the samplerate and clock source controls while the device is streaming in order to avoid changes that could mess up jack. The saffire pro controls that cause a device reset to
happen are also disabled while streaming is active.
