Anything new on your end? 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.

Best regards
Uwe
