PCM Audio With Alternate Codec (Nuvoton 8810)


#1

Greetings we replaced the WM8944 with a NU8810 the codec is configured via a legato application …
Mic->Spk pass through [sidetone] works fine as does ADC->DAC pass through if i trigger the sound system with a OpenSpeaker/Mic … call i can intermittently make clear audio calls.

Yocto has not been rebuilt to include this driver i have implemented my own driver from the application that sets the clock 2048Mhz / 8000*16 …

On “Alerting” i open modem voice RX/TX Add a DTMF detector [this works great]

i have tried opening mic/speaker and PCM RX/TX with channel 0

something seems to interfere with the PCM that makes it unreliable for repeated use.

This codec was chosen due to its integrated 1.2W amplifier and cheaper price.

If you are aware of any shortfalls or issues please advise.

[UPDATE Similar behaviour with I2S but it seems more reliable]

#2

Here is a patch i used to get it working with all codecs removed [requires unselecting / selecting options in .config

Please note the documentation is misleading the MCLK is not the 19.2 Oscilator its a clock for running the DAC’s/ADC on the codec 12.288Mhz

Audio is I2S Master [codec slave] 48000 ignore the 1.5Mhz reference in datasheet …

The patch bellow also includes the spisvc driver that can be built at the same time.
