[WP76xx] No PCM signal

Hi All

The MangoH RED default codec is using WM8944, we want change to other codec (like: WM8974).
We found a situation.
For module default setting is using internal codec (check by at!avcfg? and at!avsetprofile?).
If we change to PCM master by at!avcfg and at!avsetprofile, we can’t get PCM signal.

Do you have meet same issue?

please have a try on the following:
