Let the USB audio descriptor iteration detect configurations with more channels and larger sample size, even when the following global sysctl tunables are set to a lower value: hw.usb.uaudio.default_channels hw.usb.uaudio.default_bits This improves utility and is closer to the meaning of default. Also, do not create duplicate sample rate entries.
