Thanks for your answer. Small question so that I understand clearly.
If I use the sysdefaut option, is there any sound treatment ? Because the „hw“ option says that there is no conversation. So what’s the difference is the sound treatment between those 2 options ?
I have had already seen this possibility to connect the volume control for Squeezelite directly to my sound card but I don’t want to use it : to me, the best sound quality is achieved if I leave the squeezelite volume to 100 and, then I control the speakers volume through my HIFI amplifier. But never let any „minimized“ sound go to the DAC or the HIFI amplifier. That’s why I don’t need my DAC to control the squeezelite’s volume.
(As a remember, my installation is RP3 with M2Play&Squeezelite>USB port>USB Cable>DAC NAD D1050 (through USB Asynchronous port)>QED Reference Analogic cable>Marantz PM14S1 SE Hifi Amplifier>Focal Aria 906 Speakers)
