In the TAS2505 Application Reference Guide, Section 220.127.116.11.1 Standby mode, "all other blocks" is referring to IOVDD.
It is safe to connect/disconnect IOVDD while AVDD/DVDD/SPKVDD are on. Are you generating AVDD/DVDD externally or through the internal LDO?
It is okay to keep SCL and SDA pulled up with IOVDD, even if it is not powered on as shown in Figure 1-3.
Are you using DOUT? If not, it can be left floating.
All the best,
In reply to Caro Gomez:
It is not an internal LDO.Does pin processing change depending on whether it is an internal LDO or not?
In reply to user777540:
I was asking if you were providing the AVDD/DVDD with the internal LDO because if you do then AVDD/DVDD are powered on at the same time as SPKVDD.
The pin processing does not depend on the internal LDO.
