Hi,
I am having issues recording with the Respeaker Lite as an USB device. The recorded audio is very noisy, and my actual voice is very soft. I am using the latest 2.0.6 and 2.0.7 USB firmware from the github.
I flashed the ffva_ua_v2.0.6_output_proc0_ref0.bin from this thread and noticed that the raw unprocessed channel 1 has clearer audio than the processed channel 0 audio.

I have attached my recording for reference.
Is noise suppression implemented in the USB firmware? If not, how can I enable it?
