Echo Control Noise Reduction Mode

[hashimoto.kotaro]

Hi all,

After we deployed an SX20 yesterday, we heard echo from the SX20(TC6.0.1).

We had a test making a call between a 1700 MXP and the SX20.

When we speak to the 1700 MXP we hear our voice retrurn from SX20.

We tried settings below but none of them could help:

  Place the mic far from the display

  Disable Audio Enhancement on the display

  Enable "Game mode" on the display

  Use external audio coonector(RCA) on the display instead of HDMI

  Configure "xcommand experimental Audio EcReferenceDelay: 300"

  Swap the SX20 with another SX20

For now, the only workaround for this is to use external speaker directly connected with SX20.

Is there anythig else we can to solve this ?

By the way we found a command below on EX60(TC6.0.1).

Can we use this on SX20 to resolve the issue?

(We have no SX20 now so we can't try the command)

xConfiguration Experimental Audio Input Microphone [1..3] EchoControl NoiseReductionMode: <Normal/Aggressive>

Best Regards,

Kotaro Hashimoto

I had a similar issue and setting the echoreference to 120 pretty much eliminated the issue....

We did learn that after an upgrade the echoreference did return to default and we had to reapply the setting...

When we first tried this the EC value of 50 or 60 did nothing... I would try a larger # in the field and see if it resolved it

I would also reboot the codec after setting the value...   I know that turning on CEC mode for the HDMI needs a restart
