Hi community,

Our partner have a question about i.MX6SDL.

They are using jb4.3_1.1.0-ga, and they found 500ms mute is inserted as following code.

　-----------------------------

　hardware/imx/alsa/tinyalsa_hal.c

　　in_read function : line 2086

　　if (in->mute_500ms > 0) {

　　　...

　　}

　-----------------------------

Then, could you let me know why the mute is inserted?

Actually, this inserted mute causes unexpected mute when repeat recording start -> stop -> start -> ....

So they want to remove the mute if there is no problem.

To remove it, they want to know why the mute is inserted.

Best Regards,

Satoshi Shimoda

Hello Satoshi,

This is a walkaround for wm8962, since wm8962 has noise at the beggining.

If you are not using WM8962 then yes, you can comment that piece of code.
