Volume too low when use USB audio

I installed Mopidy-AlsaMixer and use these config

mixer = alsamixer
mixer_volume = 100
output = alsasink
buffer_time =

enabled = true
card = 1
control = PCM
min_volume = 0
max_volume = 100
volume_scale = cubic


pcm.!default {
 type plug
 slave {
 pcm "hw:1,0"

ctl.!default {
 type plug
 slave {
 pcm "hw:1,0"

But the volume is too low, about 30% of normal

Can you do an ‘mpc status’ command to confirm the volume is actually 100% and hasn’t been reduced behind the scenes by a frontend? The mixer_volume config is only the initial volume (at startup).

Can you also open alsamixer and confirm that 100% volume in mopidy is 30% in alsamixer. If they both say the volume is 100% then Mopidy-alsamixer has done all it can do and the problem is elsewhere in your system.

So where is the problem? HIFI DSD is my USB audio device

mpc status got

root@pve:/mnt/rsync/NAS# mpc status
[paused]  #0/123   0:00/0:00 (0%)
volume:100%   repeat: off   random: off   single: off   consume: off

Well, I use alsamixer to changed the DSD volume and it’s pretty well, thank you so much
