lionel 0 Posted March 2, 2022 Hello, we found the following problem on Tinker board S R2.0 with Android 7 Nougat V14.4.0.22: The audio output set to "HeadSet" changed to "HDMI" after an USB detached event (usb flash drive for instance). We can see the following message in the logcat: "system_process I/UsbAlsaManager: USB Audio Device Removed: null" Any idea? Thanks a lot! Share this post Link to post Share on other sites
