Re: 4A Configuration for Custom Audio Structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi Yiğit,

sorry, but such a configuration has not been tested, this is the reason why there are no relevant examples in the available config files.
Therefore, I am not optimistic for having this working out of the box, without changes in 4a.

Some thoughts, however:
- This should be possible from userland, to create software controls attached to the card that has playback. You will have to write a piece of software for that.
- In 4a, to have a plugin that catches theses control events and re-routes them to the card4 (see the Unicens plugin, as an example)

Best regards
Thierry

Hello,

We trying to adapt 4a-framework to our custom board. We have a specific card(card 4) for control audio functions(equalizer settings, volume change etc.) and this card doesn't support playback or capture. You can find some card control commands, card list and HAL configuration in the attachments. 

I didn't find sample configuration for similar audio structure. Where can we define that card's commands and how can we assign the commands to different roles? For exaple, we want to send Source sai1dac command to the card, when the role changes to multimedia.

Best Regards.
