Ldac not working on xa2 ultra using WH-H900N headphones.

[Culebreo]

Hello, 

I am using XA2 Ultra that has ldac greyed out in sound options fr accessories connected to WH-H900N headphones. Both are Hi-res capable and both have been updated. I have tried using developer options in the past but it would always revert back to aptx-hd codec and now ldac does not even show up in developer options. So it seems to me that ldac should be working as Oreo 8 supports ldac and headphones do as well. I would really appreciate some help in figuring this out. Thank you.

As you could see at the description page of XA2 Ultra, unfortunately, LDAC is not supported. You may use Aptx-HD, it's quite enough for hi-res audio as well. Also, WH-H900N are not that good that you'll feel the real difference between LDAC and Aptx-HD, especially with the fact you are using a mobile phone.

Thank you for your reply. I was under the impression that since LDAC was now included in OREO that it would be an option, and it was also listed under the developer options as a choice for bluetooth codec on the XA2 Ultra. I was able to choose it but it would always revert to aptxhd. The XA2 Ultra also just had an upgrade to support HI-RES audio as well. Being that the WH-H900N headphones are LDAC and HiRES compatible, as well as the phone, is there something I am missing? Any help would be greatly appreciated.
