Using the params_channels() helper when setting hw_params, results in
passing to Audioreach minimum number of channels valid for given
hardware.  This is not valid for any hardware which sets minimum
channels to two and maximum to something bigger, like four channels.

Instead pass the maximum number of supported channels to allow playback
of multi-channel formats.
