AM437x GP-EVM use of audio buffer

Other Parts Discussed in Thread: TLV320AIC3107

Hello,

In the AM437x GP-EVM, a buffer has been used to connect the audio signals on the AM437x side to the codec IC. Is the purpose of this buffer only to multiplex stereo audio output with HDMI or is it also required for driving sufficient current.

In my circuit, I am using TLV320AIC3107 IC. Should I use the buffer or not?

Thank You,

Rajat Rao
