Radeon R7 360 detects only the first display as audio enabled?

Well... the situation is - I want to connect my Digital Flat TV to my PC for watching movies.

 

Initial setup:

I connected my monitor with HDMI cable to HDMI port of Radeon card.

My TV was connected to DisplayPort of Radeon card using DisplayPort to HDMI adapter and HDMI cable connected to HDMI TV input.

Result: no sound on TV, it is also not listed in Playback Devices. Checking Catalyst options, the TV is described as "Your display do not support audio." My monitor is listed in Playback Devices and sound is heard when testing.

 

Alternate setup (without PC restart):

Connected my TV with HDMI cable directly without any adapters.

Connected my monitor to DisplayPort of Radeon card using DisplayPort to HDMI adapter and HDMI cable connected to HDMI TV input.

Result: same as in previous setup - no sound on TV and it does not exist in Playback Devices list. No any sound issues on my monitor.

 

PC restarted without any cable changes (alternate setup).

Result: my TV is recognized as Audio enabled, listed in Playback devices and sound is going there properly. But... my LCD monitor is not listed anymore in Playback devices and there is no way to test and hear sound there.

 

Ideas and suspicions:

Probably on PC restart R7 360 detects the first display connected to HDMI output and marks it as Audio enabled then stops scanning and does not add any other displays (if connected) to Playback devices list.

 

Please comment if my guess is correct.

If so, could you please provide any ideas is it possible to force both TV and monitor to be detected and listed in Playback Devices so I can switch them when needed?

Also, is there any possibility that my TV is detected and added to Playback devices list just when HDMI cable is connected, without restarting the PC?

Radeon R7 360 OC, 2048 MB, 2xDVI, 1xHDMI, 1xDisplayPort

Phillips 274E LCD monitor, DVI, VGA, HDMI
