When a transition occurs between alternate settings that do not use the same synchronization method, the substream pointers were not reset. This prevents audio from being played during the second transition.
Identified and tested with M-Audio Transit device (0763:2006 Midiman M-Audio Transit)
Hmm, I have this old device, too, but couldn't reproduce the problem. Is there any special setup with it?
OK, I could see it after switching a few times. But, also your patch didn't cure, either...
I tested this with Ubuntu 14.04 and the default madfuload package that comes with it for the firmware.
I think you need both patches to get the device to work. I split the patches in two since I think the second problem is device specific while the first one is a generic one that can happen on other devices.
I tested both at once, of course :) With my device, 24/96 -> 16/48 works, then again switching to 24/96 stalls. After that, it doesn't work no matter which mode is until I replug the device.
Hmm, now after a few retrials, it starts working. Will review both patches now.
