Sorry if my question is a bit off topic, but the folks in this forum understand the technology underlying my problem. I have a new Huawei Mate 20 x phone running Android 9.0 and a set of Jabra Elite Active 65t wireless earbuds (that worked flawlessly with my Android 8.0 phones). With the Mate 20 x they pair and connect easily. When I put them in my ears they say "connected" and if I look in Bluetooth settings on the phone they are connected for both calls and media audio. Calls come through the earbuds and I can interact with Google Assistant with them, but when I try to play music (either downloaded to my phone or via WiFi - like YouTube) I either hear a 'stuttering' noise or no sound at all. Now this is where the codec issue arises. To hear music I must go into the phone's Settings/Developer Options and change the default Bluetooth codec from AAC to SBC. I then immediately hear music. I can't save this setting, however, as each time I exist Developer Options it reverts to AAC. My earbuds work with both the SBC and AAC codecs, and if I get them to play music by switching the codec to SBC I can then change it to AAC and they continue to play music. They just won't connect with AAC set as default. Any advice on a fix or work around is very much appreciated.

You should disable "HD Audio" tick in Bluetooth device options (not in developer options).

Thank you for your response, but there are not "HD Audio" settings in Huawei's Android 9.0 Bluetooth device options. My devices (my VW car and my Jabra Elite Active 65t wireless earbuds) are listed in the Bluetooth device section but each has three options: "Call Audio", "Media Audio", and "Contact Sharing". I remember an HD Audio setting on a Xiaomi phone I had once, but that doesn't seem to be available on Huawei Android Pie.

Under developer options->bluetooth, try disabling the optional codecs and see whether it makes a difference.

Thank you, but 'disable optional codecs' is greyed out. When I am connected to my earbuds I can only change SBC and AAC the other items are greyed out.

Current results show that most devices correctly work with SBC Dual Channel and high bitrates. The test can be considered complete. Thanks for all who participated.

Why are you keeping upload the files?
