in fact via8233 has capability to output up to 6 channels (and spdif),
although most of motherboards have only two output channels.

the difference is only the implementation of the driver, so no change
will appear on /etc/asound.state.
the channels are configured dynamically according to the requested
channels of pcm.

yes, could you get more detailed info with -xvv and -nvv options?

and, please recheck under which condition this happens,
whether with the stereo samples or with the mono samples, or
whatever.

i can revert the codes only for certain chip models.
since via8233 has _only_ multi-channel playback mode, it must use
this.  but other chip models have another mode, which was used by the
old driver.  this can be enabled conditionally by checking the chip
revision number.
