Noise Reduction algorithm running on IMX6 for Audio Codec

[mujeebshaik]

Hi,

Can anyone help me out to fix the follwing issue,

We are using Audio CODEC from Wolfson micro WM8960  with Single ended MIC and One channel Speaker ( 8 Ohm – 1 to 1.5W rating),We are getting huge noise on the speaker when MIC is activated simultaneously,System works Ok if either of them i.e. MIC or Speaker is active.

Hi Mujeeb

this looks as crosstalk/noise coupling issue due to layout.

It may be suggested to check Freescale Sabre board layout

SPF-27392 p.10 WM8962 codec

i.MX6_SABRE_SDP_DESIGNFILES

and check Wolfson appnote devoted to codec layout
