If anyone has any objections, please let me know. ------------------ From: Roy Vegard Ovesen [ Upstream commit d1d6ad7f6686e208aba06b7af3feef7a7cba61cf ] Testing with a Presonus STUDIO 1824c together with a Behringer ultragain digital ADAT device shows that using all 3 altno settings works fine. When selecting sample rate, the driver sets the interface to the correct altno setting and the correct number of channels is set. Selecting the correct altno setting via Ardour, Reaper or whatever other way to set the sample rate is more convenient than re-loading the driver module with device_setup to set altno.
