Subject: Re: [alsa-devel] [PATCH 1/2] ASoC: rockchip: i2s: add 8 channels capture and lrck-mode support
We make microphone arrays with lots of microphones. Some as few as 2, many with 7 channels, and a few with 14 or more.
Can you support 8 channels with 32 bits/sample? That would work, we can just set the codecs for 16-bit samples, which would be 256 bits/frame.
Hope you had a great golden week holiday!
Thanks,
Caleb Crome
