I’m using the v4.1.3-bone15 linux kernel with debian-8.1-minimal-armhf-2015-06-09.
So yeah, it seems something broke between 3.8 and 4.1. I did look at the relevant McAsp registers and they all looked properly setup from what I could see. I'm not sure what could be wrong. Looking a the relevant code is like trying to find a needle in a haystack. Could be anything (dma engine, etc) Kind Regards, Shadi Den måndag 19 oktober 2015 kl. 03:58:12 UTC+2 skrev Rick M: > > My DTS (for both types of sound card) call for a 12MHz McASP master clock, > but in 4.x kernels, I would actually see a 24MHz signal come off the master > clock, and I think that's what led to the underflow. > I think there's more to it. My configuration is feeding McASP with an external clock from the codec board (24.576 MHz). I've verified that the internal BBB master clock is disabled by my code and that the external clock signal doesn't get doubled or anything.
