Hey everyone !
I have installed BalenaSound on 2 different RPi 3B+ and I have been able to use them as multiroom with portable speakers. However, I face a problem that seems to be not new but I could not find a solution.
When I control the master via bluetooth with my phone and put the volume at maximum on both speaker and phone, the outpout volume is still low. Much lower than if I were using the speaker at maximum volume without BalenaSound. I tried to set SYSTEM_OUTPUT_VOLUME at 100 or 98 and CONNECTION_NOTIFY_VOLUME at 100 with no success.
It seems than some people found a solution using Alsamixer but still with a lot of difficulties. Unfortunately, I have not found any ressource that explain how to install it.
Is someone able to help me or guide me to solve this ?
I thank you in advance for your help,
