ALSA driver uses audio_render component?

Fri Feb 24, 2017 3:01 pm

As per subject, I'm facing the HDMI DMA issue and would like to understand what is the way ALSA uses to render the output. My guess was that it was using the audio_render OMX component, but after some tests I made I'm not so sure about.

Also the audio_render component is forced to pass through the audioplus firmware blob, is it true for the ALSA driver too?

Just for knowledge:

I discovered, digging into raspberry kernel fork, that the driver bypass the OMX components, hence reduces the latency of the stream
