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:

@jyijyi
I have follow your step , but the result still failed.
I have set at!avcfg ,at!avsetprofile and at!avpifacepref, but still can’t get PCM signal.
If I select internal codec, the signal is correct, so I think the HW is working well.
Do you have any suggestion?

Hi jyijyi
I have try to config to F, but the situation is same as before.
Do you have try use at!avtoneplay to gen the signal?
I have test WP7607, WP7608, WP7610, the issue is same.
how about voice call?
Seems have some signal, I will test the voice call and update to you
Hi jyijyi
I have test the PCM and signal have output, but seems not meet document PCM setting.
I have experience using MC7304 voice firmware and config “at!avcfg=1,1,0,1,0,0,0,5”.
It’s working on my platform.
When I use same config on WP76xx, the PCM signal has output, but the voice like white noise.
do you have check the PCM config is working correctly?
Thanks
is there any waveform difference between your case on WP76 and MC73?
Not sure if you also need to config the external codec.
