I, I’m using RaspyPlay4 sound card, and it is supported by Max2Play. Currently, I’m on version 2.33. The issue is that the sound output level is quite low when I’m connecting the sound card to my hifi device. On level 15 (out of 30) other devices in hifi (like CD, or FM radio) the sound is good. To achieve the same loudness while connected to RPi via audio in, I have to turn it to 25 (out of 30).
I’ve tried to change the audio card to IQAudio card, and there is a volume boost setting on the interface, but when I’m dragging it to 100%, and press the save, after the page refresh, it is still on 0% (and there is no change in loudness).
I’ve choosen the RaspyPlay4 sound card just, because I saw, it is supported by Max2Play.
Thanks for your help.
