EF400 low volume issue in Linux

[stachox]

Hello everyone, I recently got HifiMan EF400 connected to HifiMan Sunadara and I have a problem with low volume in Linux systems (I tested on Manjaro, Ubuntu 24.04 with pipewire and 22.04 with pulseaudio). Even on high gain I can do max volume and I do not achieve satisfactory results. In Strawberry Music Player I set bitperfect without volume control and it did not change anything. No matter what settings I tested I could not get a satisfactory volume. This problem does not occur in Windows 11 or Android (Samsung S23), then on low gain I do not exceed 50% volume. Does anyone have an idea what could be the cause?

Check the levels in Alsamixer: https://wiki.ubuntu.com/Audio/Alsamixer

in alsamixer the level was 100% but when I pressed f6 and selected hifiman ef400 two bars appeared pcm 100 and pcm1 and it was pcm1 that was at 50%. I set it to max and now it's ok. Thanks for the help

Remember to also open another terminal while that's open and run "sudo alsactl store" which will save those settings otherwise it will reset on reboot
