I have a pi 3B+ and have set SOUND_VOLUME to 85 and the volume is still too low out the headphone jack. If I Terminal into the audio container
and run alsamixer the GUI always shows 75 as the volume level. I raise it to 85 and it works. Reboot and it reverts to 75.
release is: 471209f2ec1ec90d5ba9df3b5a031540
and list the environment variables in the audio container I see:
...truncated
SOUND_VOLUME=85
RESIN_DEVICE_ARCH=armv7hf
DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket
SOUND_MODE=STANDALONE

even though alsamixer reverts to 75 after a reboot.
