No hdmi audio output option in "System Settings"->"Sound"->"Play sound through" list(L4T R28.4)

Hi,

I’m working on TX2 R28.4.
I found that there is no hdmi audio output option in “System Settings”->“Sound”->“Play sound through” list.
It will show hdmi audio output if I used R28.3’s kernel image and dtb files with R28.4 rootfs.
So I guess this is kernel or driver issue.
Any advice/suggestion will be greatly appreciated,

Thx
Yen

Thanks for reporting this. We will check.

Hi,

Could you help try if this is due to Image or dtb?

Hi,
It’s Image

Hi,

Here is the workaround for this issue.

After boot up, open the termianl and use below command. And it will list hdmi device

pacmd
load-module module-alsa-sink device=hw:0,7 OR load-module module-alsa-sink device=hw:tegrahda,7
