Sound subsystem on RED board?

[coloradocarlos]

The default DTS has a “sound” node in the device tree as an “audio-graph-card”. I can’t find any “sound” or “audio” components on the schematic and I think this is an oversight.

Does the RED board come with some sort of audio capability separate from HDMI?

Thank you! Carlos

Carlos,

Apologies for the late reply. OSD32MP1 is connected to the HDMI Framer via I2S interface for Audio. So, the RED board does support audio through HDMI.

There are no audio codecs on the RED board. If you are looking for a codec implementation, please take a look at STM32Mp157c-DK2(https://www.st.com/en/evaluation-tools/stm32mp157c-dk2.html). OSD32MP1 version of this board is available as a reference design here: https://octavosystems.com/octavo_products/osd32mp15x/#Reference%20Designs.

Best,

Neeraj
