Hi there,
We see this issue/bug before. thanks.
Note: Limit for developer using 6-Mics Circular Array Kit(or 4-Mics Linear Array Kit) doing capture & playback the same time:
capture must be start first, or else the capture channels will possibly be disorder.
playback output channels must fill with 8 same channels data or 4 same stereo channels data, or else the speaker or headphone will output nothing possibly.
best rgds
Bill
