imx6 android9.0 use sgtl5000 on HDMI

[minyou]

Hello:

I want to ask!

On imx6 android 9.0, when I use HDMI, sgtl5000 has no sound effect. I should connect HDMI and switch to HDMI sound effect card.
Is there a patch that can output sound effects at the same time when HDMI sound card and sgtl5000 are connected?

Hi minyou

sgtl5000 is not supported on nxp i.mx reference boards, one can look at third parties,

like sabrelite board:

Hi igor

sorry , I use imx6q, I can use sgtl5000 on android 6.0
I connected HDMI to android 6.0, my sound effect can be output from sgtl5000,
But I can’t let him output sound effects from sgtl5000 in HDMI mode on android9.0.
I am guessing whether it needs to be modified in tinyalsa_hw.c?
