Enable PCM2 I2S output on QCC3008

12345678bt

Hello,

I want to enable the I2S output on the PCM2 output of the QCC3008.
I have set all the primary and secondary to "I2S" with "Instance 0", but I get no output.
Setting it to Instance 1 or Instance 2 also does not change anything.

What do I need to change in the settings to get this working?

之前也测试过，示波器可以看到I2S信号，但是没有声音，可以进ufe工具看看dsp状态。

You got signals on the PCM2 port? I measured with the oscilloscope, but on my module there is no signal. What are your settings?

If I open the UFE tool it says "does not identify itself as a recognisable algorithm", even when I play music. Do not know how to fix it. I can use PStool and ADK configtool without problems

I'm sure the I2S signal can be output by I2S2(PIO6,7,8,9).Please check if the PIO6,7,8,9 were not be set as the other function(i.e. button or else)
