Hi everyone,

Has anyone managed to enable separated dual I2S outputs?
Single I2S output is OK, but I need dual output to drive 2 separate amplifiers.
The datasheet of the QCC3031 says that the chip can do 3 separate I2S outputs (7.1 Audio subsystem features), but I have not seen anyone doing this.

Can anyone help me with this issue? How would I set this up in the ADK for dual I2S? And will it be possible to adjust both I2S settings in the configuration tool?

My main goal is to be able to drive two I2S amplifiers with separate DSP settings, hence I need two separate I2S outputs.

Sorry for english, and thank you.

没啥意义啊，一路I2S输出可以接2个功放啊，

Not if you want separate DSP settings. I want to be able to have stereo speaker with woofer and tweeter. Therefore I need 4 channel DSP allocation. I need I2S for both primary and secondary outputs in DSP.

关于明天的事，我们后天就知道了。
