I know from Lothar that he invested quite some time to debug his hardware setup, tested the codec instead of the i.MX28 as clock provider and several more things. I also spend some time on this issue and we both hope that Freescale/NXP can help in better understanding the issue and hopefully can come up with a recipe to make concurrent recording and playback on i.MX28 work. Lothar is in contact with Freescale, too, but up to now with little success. The company I'm working for at the moment would also welcome a solution here.
