Bose Binding Power/OperationMode issue

Hi,
I absolutely love the bose binding!
So far it’s working nicely for my Soundtouch300 and Soundtouch10.
But I found a weird behavior:

When I turn on my SoundTouch300 to AUX channel, openHAB won’t show Power/OperationMode correctly.

But, as soon as I go to channel Spotify or Bluetooth, I see the correct Power state for both (I changed volume manually):

Here is my setup:

bose.things:

bosesoundtouch:device:300 @ "LivingRoom"  [ host="192.168.178.22", macAddress="xxxx" ]

bose.items:

Switch   BOSE_SoundTouch300Power    "Bose SoundTouch 300 Power" <switch>  {channel="bosesoundtouch:device:300:power"}

sitemap

Switch item=BOSE_SoundTouch300Power label="SoundTouch 300 [%s]"

logs when turning on SoundTouch300 in AUX channel:

Question:
Is it possible to get the correct binding for AUX channel for power and operation mode state?

Thanks!
