Q: Is it possible to connect a PC through analog and Bluetooth receiver while the PX5 is also connected to a PS3/Xbox 360 optical cable?
A: No; when a S/PDIF cable is connected to the Digital IN jack in the transmitter, the analog inputs to the transmitter will be switched off. In order to use the analog inputs you will need to unplug the S/PDIF cable.
The Bluetooth operates completely separately from the transmitter, so anything happening over Bluetooth (e.g. stereo audio over A2DP or headset functionality on a cellphone/PC) will be unaffected by the transmitter.
