Have not found a solution to this. However, this is also a bad solution because the sound via Bluetooth is usually out of sync. The Toslink output with an ADC is the better solution, also in terms of sound quality. I use: Oehlbach DA CONVERTER
Oehlbach DA CONVERTER - 192kHz / 24bit Audio Support (D/A Converter)

no problem with the receiver, which also has bluetooth. often listen to music via mobile phone. unfortunately bluetooth on the tv doesn't work with the mobile phone. it only works for streaming the screen on the mobile phone on the tv, which is very cool.
