I started using balena sounds recently I very much like the approach of managing a fleet via the balena dashboard!
However, after setting up my fleet I ran into an issue where the volume across my two devices is largely imbalanced. Even when I set the volume (using the
SOUND_VOLUME env var) of device A to 1 and the volume for device B to 100, still the volume of device A is way too loud and device B is barley audible. That is why I assume there is something fishy, or I am doing something wrong. When I run the devices as standalone devices I am able tune the volume of the devices properly, which means the speaker+dac combination works in general. Any hint would be appreciated.
My setup looks as follows:
|device||balenaOS||balena sound release||DAC||SOUND_VOLUME||problem|
|Raspberry Pi 3b+ 64bit||2.80.3+rev1||df4c8eb||HifiBerry Amp2||1||too loud|
|Raspberry Pi 4b 64bit||2.88.5+rev1||df4c8eb||HifiBerry Mini Amp||100||too quite|
Note, I also tried different combinations of the
SOUND_MODE env var, unfortunately without any success.
