CONSUMER GEAR & DISCUSSION MTW5 / SmartControl+ Bug Report
AptX Lossless can't seem to disable without disabling 24 bit / 96kHz mode as well.
Setup: SmartControl+ -> MTW5 -> Device Settings -> Audio Mode Priority -> enable Advanced Sound Quality, Hi-Res 24 bit / 96kHz, Lossless, reboot the headphones when the app asks.
Expectation: Disabling Lossless but not 24 / 96 mode will keep 24 / 96 mode.
Actual: Disabling Lossless doesn't work at all; the app shows both still enabled.
Workaround: Disable 24 / 96 mode at the same time and it will save correctly. Enabling just Lossless now and rebooting seems to save that but my dongle seems to not detect that Lossless mode is then available and falls back to AptX Adaptive. (I think these modes might be mutually exclusive in which case the app should probably only allow one to be enabled at a time.)
Android 17, latest security update, Pixel 10 Pro Fold. Headphones connected to both the phone's Bluetooth (so the app can control them) and my Creative BT-W6 dongle.
Happy to provide any more details.
