And here's the promised emulator build (from aemubins gmail account that we use to distribute debug binaries like this):

If you still don't get symbols from that it should be possible to build the emulator itself on macos:

install repo from depot_tools https://www.chromium.org/developers/how-tos/install-depot-to...

    pip install absl-py
    pip install urlfetch
    mkdir emu
    cd emu
    repo init -u https://android.googlesource.com/platform/manifest -b emu-master-dev --depth=1
    repo sync -qcj 4
    cd external/qemu
    python android/build/python/cmake.py

    # run
    objs/emulator -avd avdName -no-snapshot

Debugging:

    # when it spins:

    # method 1: go to activity monitor -> sample process, send over the result

    # method 2: lldb
    lldb
    process attach --pid <pid-of-qemu-system-<arch>>
    bt all #send it over

    # method 3: guest process taking CPU
    adb shell top

Sorry, I'm not an expert. What am I supposed to do with the emulator-symbols.zip?

Replace your current emulator install; delete $ANDROID_SDK_ROOT/emulator then unzip it there so theres $ANDROID_SDK_ROOT/emulator again.

$ANDROID_SDK_ROOT, if not set, should be set to the SDK location in Android Studio > Preferences > Android SDK (SDK path will show up there).

Set it in your ~/.bash_profile too so it's there next time for running the emulator from the command line.

The AVD config.ini can be found in ~/.android/avd/nameofAvd.avd/config.ini .

Interesting, sounds like a live loop in some audio thread somewhere. What's your audio setup and AVD config.ini? I might be able to reproduce on my Mac.
