Second format for input/recording stream in USB Audio projec

Post by ffomich »

Hi!

USB Audio Design supports 3 format for output/playback (24, 16, 32 bits) and only one format for input/recording (24 bits). 

Is it possible to add second format for input/recording in UAC1 mode?

 

What I do:

1. Change STREAM_FORMAT_INPUT_2_RESOLUTION_BITS from 24 to 16

2. Add Alternate Settings 2 for input interface.

I missed something?

Yes it can be done, it would require quite a bit of copy and paste for the descriptors I would say.
