Hi all,

I am working on an system APP, in which I want to have a seperate audio playback route as the one used in Phone call. I am able to create the audio topology for the same. And is associating with the Playback devices, this I confirmed in QACT tool.

The added topology must be reflected in the "acdb_default_data.c" as through the QCOM doc. How to modify this file and use the same for particular use case. Any information on the same will be very helpful.

Thanking you.

Hi all,

I am able to modify the acdb_default_data.c file, and have inserted my own topology and audio device use case. But when I want to use my own use case, that is not getting reflected in qDSP audio path(verified using QACT) when I am replacing the acdb data files in the device. Can any one suggest whether the steps followed is fine to create a new topology.

Is there document that would explain the correct sequencing of DSP blocks while creating custom topology?

For example, for no obvious reasons we got non-working topology by swithching the order of MBDRC and IIR filters.
