Capture or play back audio with the specified number of channels. If more than two channels are used it is recommended to use the --channel-map option below. Defaults to 2.
--channel-map=CHANNELMAP
Explicitly choose a channel map when playing back this stream. The argument should be a comma separated list of channel names: front-left, front-right, mono, front-center, rear-left, rear-right, rear-center, lfe, front-left-of-center, front-right-of-center, side-left, side-right, top-center, top-front-center, top-front-left, top-front-right, top-rear-left, top-rear-right, top-rear-center, or any of the 32 auxiliary channel names aux0 to aux31.

--no-remix
Never upmix or downmix channels.
--no-remap
Never remap channels. Instead of mapping channels by their name this will match them solely by their index/order.
