I have no audio from Anbox. (Only app I use is Chinese skill, but even in audiosettings the ringers dont play when I select them. Don’t know where to go to get more info or what info do you need? (Since most info I normally submit would come from the “kernel” settings page which is greyed out.
Although it shows version 7.1.1 for the version of Android.
THat’s linux Mint xfce, running pulse audio. All other apps work with audio, just anbox does not.
