Respeaker with C2 using I2S

Unread postby IshtiaqShaheer » Tue Oct 10, 2017 10:52 pm

Hi,
I connected Respeaker with USB cable to C2 and a speaker with amplifier to Respeaker to get the output.
But there is being some noise from the speaker, so I was thinking to do it with I2S.
So may I know how does this I2S works? I'm using Android in C2, so will be there any coding for I2S to work?
I'm completely new with this protocol, so please do help me!
Thanks in advance

If Respeaker uses the UAC standard protocol via USB interface, you might need to edit audio_policy.conf file manually to enable audio input.

Ya currently we're connecting using USB but I want to know how to use this I2S interface to connect it.
And if we connect is there any sort of programming to be done to let it work?

You can try I2S signals on J7 connector. Sound output should work out of the box.

But there is no I2S input path and the microphone input won't work.
