UDA13XX codecs I have checked I would say it's possible to have multiple
devices working on same bus.  The slave devices are selectable by 6
most significant bits of the address byte and the device addresses
seem to be unique at first sight.

"In the event that the UDA1341TS receives a different address, it will
deselect its microcontroller interface logic." (ch. 7.19 [1])

However I can't answer yes for sure, I've never seen multiple device
operation mentioned explicitly in the datasheets nor such an hardware
configuration.
