Choppy USB audio on i.MX53 chipidea with 4.4 kernel. Ok in 4.10

2017-02-21 Thread Martin Fuzzey
Hi, I ran into a problem of "choppy" audio when using a USB codec on a i.MX53 (with the chipidea driver) The problem occurs on 4.4.47 but not on an old 3.19 It also does not occur on the latest 4.10. The codec is : Bus 001 Device 003: ID 08bb:29c0 Texas Instruments Japan PCM2900C Audio CODE
