Thank you very much, vdharani.  With your modification, my usb speakers
started to play under the correct key.  But I can't set volume yet.

	% echo volume 0 > /dev/audioctl
	% madplay 01.mp3

The above still plays with the loudest volume.
I attached the logs for:
	- usbaudio -V
	- usbaudio -Vd-1 -v x
	- usbd -dv

Any suggestions are appreciated.  Thanks
