From: Ermin Sunj <redacted> If the codec is not the clock master, the MCLK needs to be synchronous to both I2S_SCL ans I2S_LRCLK. We do not have that on Haikou, causing distorted audio. Before: Running audioloopback.py script on Ringneck, 1kHz output sine wave is not stable and shows distortion. After: 10h stress tests audioloopback.py failed only one time. That is 0.00014% failure rate.
What is TSD? Why it is in the subject prefix? Please use subject prefixes matching the subsystem. You can get them for example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory your patch is touching.
